Daddy was of Scottish/Irish descent. The Scottish clans kept very detailed records of their generations, so this made the search for ancestors easier to follow.
His mother was a direct descendant of the Stewart of Scotland, from which the Kings of England are also descended. My daughter's 22nd generation great grandfather was Robert II, King of Scotland Stewart--the first Stewart king.
I found this copy of the registry of the marriage of Daddy's mom and dad, the starting place on my quest through the years.
