Problem #1: After a temple ordinance is completed, "FamilySearch" adds REDUNDANT information (an alternate name that matches the record name). If they need to add this information, the least they could do is call it something other than "Birth Name". Perhaps, "Name when ordinances were completed" is more accurate. (The folks at FS have remarked that this feature helps when doing searches and finding duplicates, in case the record name gets changed. I tend to think there could be a better option.)
Problem #2: When I noticed the redundant alternate name, I deleted it in several records (findarecord.com makes it very easy to see which records have "identical names"). In some of the records, however, something VERY STRANGE happened after I deleted the redundant name. From what I can tell, the alternate name appearing right above the alternate name I just deleted BECAME THE RECORD NAME and also disappeared! And in the history it shows I changed the record name. Which I certainly did not! I only deleted the redundant alternate name.After checking the FamilySearch.org Family Tree, I do find that an "Alternative Name" has been added by FamilySearch on or about the same day the ordinances were performed. This added name seems to be identical to the name that was submitted. A further comment indicates that this is a convenient way to be notified that the ordinance work has been done. Subsequently, blogger Amy Archibald of the Revealing Roots and Branches blog, sent me several examples from the Family Tree.
This is not the problem I have outlined in my posts about cleaning up the Family Tree. Those entries come in with a reference to a "Birth Name" not an "Alternative Name." The Alternative Name issue is more serious because if the name is different than the one listed in the Details section of the entry, there is a need to verify and document the Alternative Name. If, as observed, FamilySearch is using the designation of an Alternative Name for some other purpose this could create some difficulties.
I do not have a solution to this problem.
