That’s not true. Gashi I Gurit is a tribe in itself and has nothing to do with Krasniqi, except for sharing a TMRCA of ~ 900ybp with them and Nikaj. Gashi as an anthroponym has been mentioned since 1485, then in 1634, as a tribe / village in 1636 by Bardhi, in 1651 by Bogdani etc.
Frang Bardhi in the visit of 1634 in the village of Gash, which is supposed to be GegHyseni, says that the first of the Gashi tribe was Pjeter Spani, the ruler of Pult. Based on the latest genetic studies, it seems to be kinda true. According to Elsie, Gashi was the first tribe of Tropoja and lived there long before Krasniqja came. Based on its tribal scheme, but also based on the TMRCA, Krasniqja must have come to Tropoja around the years 1550-1600.
In 1689 we have the letter of the "Krenat e Gashit", addressed to the Pope of Rome, where they asked for priests for their churches.
Right after the letter of the leaders of Gashi, somewhere between 1693 - 1695, the Pasha of Peja, conducted an expedition and destroyed whole Gashi and moved all its inhabitants to the Dukagjini Plain. That was a very big turning point for the Gashi tribe. This tribe that settled in the Dukagjini Plain at that time was still Catholic, and today is scattered throughout Kosovo, in Llap, Gollak, Anamorave, as well as in Drenice and Dukagjini Plain. That tribe was Gashi I Gurit, that is, the real Gashi, the descendants of the noble medieval family of Spani, who has no blood connection with the Bardhet e Gashit(Whites of Gashi) which today live in Tropoje, nor are they "integrated" in the tribe of Krasniqi as you claim. After the settlement of Gashi i Gurit in Kosovo, Krasniqi began to migrate west and populate the old settlements of Gashi in Tropoje.
Bardhet e Gashit on the other hand, multiplied and expanded their settlements, and since mid 1700 until today, are known as synonymous with the Gashi tribe. Today they inhabit all the villages of Gashi of Tropoja, except Luzha which is Gash i Gurit(J2b-L283) and which was formed by the Aga of Botosha sometime after 1700. Bardhet together with Shipshaj, are both E-V13>PH2180. In Kosovo, although there are few tested, most of the Gash are Gash i Gurit (J2b-L283). Normally, there are families that have joined the Gashi tribe in Kosovo as well, but what is more important, so far, no tested Gashi brotherhood of Bardhi or even Shipshan has been encountered yet.
To be frank, Gashi i Gurit is not Krasniqe, nor Krasniqja is Gash i Gurit. Not even Nikaj belong to the Krasniqi tribe. The real Krasniq are those who share a TMRCA of 500ybp and who are the descendants of the Kolmekshaj, Hysenmekshaj and Kolgecaj brotherhood.
The last common ancestor of these three tribes(Gashi i Gurit, Krasniqja and Nikaj) lived about 900 years ago. The paternal line of the Gashi tribe has been separated since then, while the Nikaj and Krasniqe share even closer common ancestors, until about 600-700 years ago. Also in this subclade is an Arberesh of Italy and an Albanian from Syria, who claims to be from the Dukagjini tribe. If this is true, then it once again confirms the origin of Gashi i Gurit from the noble medieval family of Spani (Pjeter Spani, Leke Spani), because according to M.Sufflay, the Spani was the same tribe with Dukagjini.
Long story short, do not mess around with history.
