I read your inquiry and don't know if this fits but:
In my genealogy research I find "William McCrea Daltangan" born 1736 in Scotland. I believe the "Daltangan" refers to his area of birth perhaps. His Father was "Hugh McCrea" born about 1700. William was married to "Jean Blain" born 1742 in Scotland. William and Jean had a son, also named William, born 1776 in Scotland who married a "Janet Galloway" unknown date of birth. They had a son named "Peter McCrea" born 1827 in Glasgow, Scotland. Peter married "Mary Proudfoot Beattie (Beatty?} in Canada. I show Peter having died in Colorado, USA in 1900.
If you have anything on William McCrea Daltangan or his father Hugh I would appreciate anything.
