If it should assist analysis of the apparent problem, considering other comments posted: My successfully-uploaded GEDCOM was 318KB and contained strictly vital data on my ancestors (detailed BMD dates & places). It's still on the FTDNA website, working fine. Only my parents were rendered private - properly, by default. The births of the six-generations included were uncomplicated by any double-dating because they all occurred after 1752. I've researched more extensive ancestry, but have excluded earlier generations because, while I've had wonderful success with 23andMe, I'm skeptical that identifying mutual ancestors among "matching" contacts beyond fourth cousins is realistic. It's not just the IBD vs. IBS quandary. Quite simply, all of us have far too many fifth cousins for any definite correlations. At that distant relationship, there's no way that you can be certain that the mutual ancestor you and a cousin have laboriously identified through genealogical comparison (though worthwhile endeavor in itself) is definitely the ancestor responsible for a matching DNA segment. Fortunately, I can refer curious contacts to my family-history website that extends to an arbitrary twelve-generation cutoff.

However, this was the first time that I had uploaded any GEDCOM to FTDNA, having no need to replace previously-sent separate maternal and paternal GEDCOMs, which FTDNA said, in a note during the procedure, that it would eventually be eliminating in favor of combined versions. So, there may be some problem when one has to replace previously-sent GEDCOMs. Charles Acree
