I have read whole Hermaszewski’s tekst, his clues contradicts yours. ;)
1. Monk the author of the book was wery well informed about history of local community, so it is likely that he knew well how to distinguish Poles from Czechs.
2. The knight had Czech origin but he had Polish wife and he leaved among Poles, so the most probable is that he used Polish language to speak with his wife.
3. Polish ethnicity was already created in feudal class in 11
th century. The best prove for that is the crisis of state 1034-1039/40. Duke Kazimierz was forced to leave the country, he get back fife years later and took the throne the only one who had power to oppose him was Miesław cześnik of Polish king Mieszko II, he was defeated at the Battle of Pobiedziska in 1041.
As I promised here are my points why there were no population replacement in Poland during migration period:
My map made to clarify my points.

1. Analysis of Mielnik-Sikorska et al.(2012)
Table 4. Red points on map are representing samples from table.

Rst values shows that modern northern Slavic population reveals ancient division in two groups of proto-Slavs northern one and southern one( reported before in Morozova et al.(2011) – mtDNA).
According theory of spread of Slaves in late antiquity and early middle ages the roads of migration to the west leaded from Ukraine/Belarus to Poland and from Ukraine through Carpathian mountains to Pannonian Basin and then to Bohemia, Alps and Dinaric Alps( drown in orange).
Southern road:
There are two samples from Lviv so values will be written that way: 1/2
Distance in a straight line.
Lviv – Użhorod 0.007/0.002 distance 185 km (barrier Carpathian Mountains)
Lviv – Bratislava -0.004/0.005 distance 540 km
Lviv – Bohemia 0.018/0.028 distance 650 km – 0.0028 per 100 km/0.0043 per 100 km ( marked on map with brown line)
It is clear that these populations are very close to each other, what supports mass migration from Ukraine to Pannonian Basin in early middle ages.
Northern road:
Lviv – Lublin 0.042/0.046 distance 188 km – 0.0223 per 100 km/0.0298 per 100 km ( marked on map with brown line)
Concerning that Lviv was part of Poland from 1340 to 1795 but it was influenced by Polish culture and people until 1945. There are many known relations from 14
th and 15
th century that many Polish settlers converted to orthodox faith and assimilated in to local Ruthenian population. So probably that Rst value could have been higher for medieval Population from Lublin and Lviv. Rst value increases 7 to 10 times faster with distance from Lviv to Lublin then from Lviv to Central Bohemia while on second road there are multiple barriers for migration.
Alternative road is from Pripet marshes.
Ivanava – Lublin 0.0075 distance 228 km
It seems that this are very close related populations, but Ivanava sample comes from YHRD where it is described as 35 haplotypes so we are dealing with little sample size.
This closeness could be caused by mentioned by Nestor migration of
Vyatichi and
Radimichs, because Ivanava is small Town in sparsely populated area this could be some relic of this migration( migration marked in green on map). One more supporting fact is that in Underhill et al.(2009) M458 in Central Belarus was confirmed only in 4% of the sample while in Poland near Lublin in Zamość it was found to nine times more frequent.
2. Good indicator to show differences between Polish and Ukrainian/Belorussian populations is to check frequencies of subclades of haplogroup I and combined with frequency of haplgroup R1a. (various studies, reference points marked in yellow on map)

To analyze data further I need to calculate relative frequencies to haplogroup, which is the best to help me trace migration of Slaves. I2a1 is very rare or absent from places where modern Germanic population lives and is virtually absent from areas settled by ancient or early medieval Germanic people. I have excluded I2a1 – M26 from relative frequencies; 1 sample from Kashubia and three from Bohemia because it is virtually absent from Central and Eastern Europe.

Conclusion:
Changes of relative frequencies of analyzed haplogroups is clinal. Final changes along analyzed road are around 2 and 3. This changes occur in two steps, with similar rate per step, what makes genetic drift not appropriate model to explain results. Simultaneous migration and assimilation of some local significantly smaller groups then immigrating one explains observed changes in relative frequencies.
The composition of assimilated groups could have been complex, in Panonian Basin before Slaves lived many ethnic groups of different origins, Germanic, Celtic, Sarmatian, Panonian( Illyrian) and Dacian tribes. This assimilated elements probably ware similar to modern Bavarian but poorer with I1 and richer with R1a. Slavic population of Bohemia could have been enriched in R1a from Oder and Vistula Basin by migration through Moravian Gate ( marked with two red lines and green arrow on map).
I tried to find haplogroup composition of that pre-Slavic population of Bohemia, here are results:

Modern Czech population could be mixture of that pre-Slavic in 40% with that from Bratislava in 60%.

Situation in Northern European Plane during migration period, was marked by population outflow to south and west, and population dropped by two-thirds (in Vistula Basin ). From eastern part of this area in Pripyat Marches and middle Dnieper Slaves migrated to Vistula, then Oder and next to Elbe. Before migration period basins of that three rivers were inhabited by Germanic tribes. The only one group which was assimilated by migrating Slavs was this Germanic people. If migration from Polesia to Vistula Basin was mass scale population movement then population of Vistula Basin had to be richer in R1a poorer in all I subclades especially in I2a1 then modern Polish population. Modern Sorbs and Kashubians fit to this description, here is sample calculation:

This result is range of polish samples. So it is highly possible that immigrants from Polesia spread in Vistula Basin among people with genetic composition similar to modern Sorbs. If that would be truth, eastern Germanic tribes were genetically closer related to Protoslavic population then to any other. This theory is supported by results of commercial studies which shows many R1a subclades specific to Polish and central European area, like
L260 and L365.
Changes of relative frequencies in two steps from Polesia to Sorbs is too high explain this by migration. More appropriate model describes that modern Polish population was created by much more migration events and much longer time then 1500 years. To describe Slavic migration by northern road minor migration with large scale assimilation, with decreasing influence of migrants from Polesia from about 40% in Eastern Poland to virtually 0 on Baltic coast and middle Elbe river is much more resonable. Unfortunately the only available data are for middle and lover Vistula Basin so we have big gap in central, southern and western Poland.
You have quoted Omelijan Pritsak’s work, but I do not thing that this is considered as good analysis of ancient texts, Tacitus and Pliny(
Naturalis Historia, IV-97) mentioned Veneti/Venedi in Eastern Europe, in forest area north of Black Sea, it fits localization of Slavs. Later Jordanes relied on this.
Tac. Ger. 46:
“As to the tribes of the Peucini, Veneti, and Fenni I am in doubt whether I should class them with the Germans or the Sarmatæ, although indeed the Peucini called by some Bastarnæ, are like Germans in their language, mode of life, and in the permanence of their settlements. They all live in filth and sloth, and by the intermarriages of the chiefs they are becoming in some degree debased into a resemblance to the Sarmatæ. The Veneti have borrowed largely from the Sarmatian character; in their plundering expeditions they roam over the whole extent of forest and mountain between the Peucini and Fenni. They are however to be rather referred to the German race, for they have fixed habitations carry shields, and delight in strength and fleetness of foot, thus presenting a complete contrast to the Sarmatæ, who live in waggons and on horseback. ”
Here is map showing Zarubintsy culture( green), and location of Bastarnae( violet), Sarmatians and Scythians( yellow). Fenni ware in upper Oka river and north to the upper Dnieper. Judging from this description Veneti fits perfectly green area.

BTW some signs of name Venedi are visable in names of Russia in Finic languages( Fin. Venäläiset, Est. Venelased, ), and name for Western Slavs in German Wenden.

I know this line of argument, it does not confirm the roots of the Slavic languages in Milograd culture. Sufficient for the existence of such relationship is about 800 years between rise of Zarubintsy culture and Slavic expansion. Remember that in Polesia are also many Baltic hydronyms that just may be associated to Milograd culture, otherwise there is no place for them.
The most important is basic assumption that cultural replacement results in change of cultural attributes, one of them is language. Of course archaeological studies are performed on dead objects, so we cannot ask them about their owners language.
