Thanks, Terry. That helps some. The next 'tangled skein' is in the Combs/Combes branch connected to the Archdales, and I've (as you suggested) started a discussion there to see what additional info might be come from the managers. There is one place where a profile is both a father and son to the same other profile, and many of the children have birth dates before either parent. One of those 'managers' is curator, so hopefully "we all" can get it sorted out.
