There are some articles in MD Historical Magazine, 1915, Vol. 10, by Francis B. CULVER, on the Merryman Family, but I only have the early parts that connect to my line. I don't see any Archibald in the parts I have.
There is also extensive information about the family in Robert BARNES' Baltimore Co. Families, 1659 - 1759, but Archibald isn't mentioned.
