I recently saw a book in a library in LaPlata, MD which dealt with Catholics from Southern Maryland who removed to Kentucky.I don't know if these men were part of that group.I have a sheet from a book (no title) which mention:
"Henry O'BRYAN was born in Charles County, Maryland in 1783 and moed with his parents to Nelson County, Kentucky in 1792.He married Mary MCATEE in Kentucky on November 27, 1809.A hatter by trade, he died December 14, 1858. (Ref: KA 1:3, January, 1976, p. 163)"
"Peter O'BRYAN married Jane Gardner and moved to Nelson County, Kentucky from St. Mary's or Charles County, Maryland, with his two sons, Lewis and William.(Ref: KPG 1:4, Oct., 1979, p. 55).
I do not know what these references mean.I AM NOT RESEARCHING THESE PEOPLE, AND HAVE NO FURTHER INFORMATION.
