Okay. . .
Catherine HARGAN married Joseph FAS, in Maryland on 3 Nov 1778.That would put her birth, say about 1758, if she was 20 years when she was married.

Would you let me know of the records that you have that show he has a daughter named Catherine?Daughter-in-Law, yes, but I am still inclined to think Catherine is one of the two sisters that came over with him. I am willing to change that thought.Records tend to pop up quite unexpectedly in genealogy, as I've found out.
