New York RICHARDSONs?

Ralph's dna results arrived at last, and show a 34/37 match with a descendant of an Adam RICHARDSON, born 1835 New York of Scottish parents (ie rather distant, but definitely worth investigating).
Hardly a conclusive match, and certainly no immediate candidates spring to mind, but given Adam had a middle name of BROWN, just possibly he's a descendant of this family in my LornaPotential database: Adam and Margaret (BROWN) RICHARDSON, married 1788 Hawick, ROX.
I had researched them for possible connections to "our" RICHARDSONs because both families were from the Borders, and had ended up in Edinburgh, one in Lauriston Gardens, the other in Lauriston Terrace (I've not found out how close these streets are).
If there are any male RICHARDSON descendants of Adam and Margaret out there willing to test this theory out further, we'd love to hear from you.

Also decided to help out by joining the indexing project at FamilySearch.
Least I can do for all the help they've given the genealogical community over the years with their filming of original records.
I'd been holding off in that I thought I might not be able to commit enough time to make it worthwhile, but a "batch" is a very manageable size, easily done in a few minutes (or at least it was for the two initial batches of Cheshire records I've contributed so far).
