THOMSON or NEILSON?

Take your pick?

My WorldConnect database LornaHenderson has been republished to include, amongst all other updates, some of the family/ancestry of Gilbert THOMSON and Margaret NEILSON of Wishaw/Shotts/Cambusnethan, Lanarkshire (emigrated to Pennsylvania).
Somewhere back up either family's ancestry is a common ancestor to several descendants of William HENDERSON and Helen Sinton WIGHT.
But which side is it, the THOMSON or the NEILSON?

It could be yet another clue to the elusive Amelia MILLAR of Kippen's ancestry?
Or some other curious connection from the Scottish Borders ancestry of Helen Sinton WIGHT?

If you recognise any of these names, particularly if you are a descendant of a sibling of either Gilbert or Margaret and would be willing to see if you get a dna match with any of us who inherited this bit of shared dna, please do get in touch.  We mostly use FamilyFinder*, but as long as the dna file is on GEDMatch.com, comparisons are possible across testing companies.

The theory is that a descendant of a sibling of Gilbert's or Margaret's should show up as an excellent match with the descendants of Gilbert and Margaret who have a good match between second cousins.

If one side of the family also show up as a match to the HENDERSON/WIGHT descendants but the descendant from the other side's sibling doesn't, we've figured out whether it is THOMSON or NEILSON.
