Well, I was mainly looking for more information about 4 families from whom I descend: De Correia, Pacheco, De Medrano, and de Toledo de Alba, but also others. Wikipedia only offers a little information about these families in general. Both of my parents have ancestors from these four families, though my mother was born in Texas. I think there might have been a Pacheco ancestor born in either Mexico, unknown, of Spanish descent or born in Portugal, though I don't know when exactly, sometime in the 1700's is my guess; on ancestry I have Pacheco relatives who claim descent twice from Francisco Pacheco de Bocanegra Y Cordoba born in 1560, but other relatives seem to be Pachecos who immigrated from Portugal.
My dna analysis says of male ancestors in my dna I have House de Correia 1.13 %, House Pacheco 1.09 %, House de Medrano 1.04%, House de Alba 0.39%, so these are relatively recent Iberian ancestors, some from the 1700's no doubt, and some from likely the 1600's or mid to late 1500's. My father is from Scotland, but he has an ancestor who was Spanish whom I know was part de Correia (he has de Correia dna 1.51%) as well as Pacheco .70%, de Medrano .60%, and Toledo de Alba .19%. I think his Spanish ancestor was born abt. 1800 and came (with her parents possibly) as immigrants to Scotland before 1822. I don't know why they left Spain for Scotland. According to a dna analysis I had my father undergo, he also has long ago de Sousa .05%, Andrade .05%, Ramirez de Arellano .03%, and trace of Carvajal ancestry as well, but this is so far back I wouldn't even begin to know who these ancestors were or be able to find them with any degree of certainty. However, any information that you could offer me about all of these families or where to look for lineages would be appreciated!
