Hi Michael, Try this. There are a lot of "no info" Gedcom profiles. Some with erroneous date info that need cleanup. Did you try contacing Profile Manager?
(1) Did you try checking down the Descendant List? (Family Tree). If you have any matches here, they are probably the same.
(2) Try pulling a census for Maj. Mason (or son) to see list of children and that Wiki contains "complete" info -- for any possible match.
(3) If no match (or match), paste census "cite" on Bio; do quick bio update and indicate "no connection to contemporary [[Mason-6362 | Maj. William Mason]]
