My line of Drinnon's was spelled Drennen until 1800 then it switched to Drinnon. We are Scots-Irish. Records verify my ancestors settled in both countries. Drennen is the bastardized spelling of Draighnain which means black thorn. I have in my possesion documentation bearing not only the family crest but also the words Nec Opprine Nec Opprini, which means neither to oppress nor to be oppressed. Drennen first shows up in Galway as one of the oldest families in Ireland. I have been told that there is a Castle somewhere in Scotland bearing the name Draighnean. Whether or not this is true, I don't know. But the document I have pertaining to the origins of the Drennen's is a certified guaranteed acurate document taken from Scottish records which also includes that at one time the Drennen's were Clann Drennen but have sinced been absorbed by Clann Drummond. I can not percieve why Scottish and Irish historians would tell tall tales about the lineage of a family especially one as old as the Drennen's. Our name shows up in the earliest of Irish records which makes us an ancient Clann, and they also appear in early Scottish records. That being said, it is true that it is very difficult to trace the Drennen's in Ireland and Scottland. I myself am stuck in 1680 County Antrim, Ireland due to the lack of availability of church and province records. I guess, I'm just gonna have to go on vacation to Ireland to solve the many mysteries of my family prior to their coming to America in the early 1700's. I have researched my grandmother's family for over 15 years. The name Drennen is in the book of Scottish Clanns. There is a website that has information about the history of the Drennen's, but for the life of me, I can't remember what it is. I have it in my files at home, so I will contact you with that info later this week.
