I just ran into some TreeShare behavior that I found unexpected. It may well known to TreeShare users who make heavy use of Ancestry and TreeShare together to bring data from Ancestry down to RM. But the behavior was unexpected to me.
I created a test Ancestry tree with two real people I used real people so I could get Ancestry hints. I entered the following data and nothing else at all.
Alva Peters, born 1870, died 1942
Alva’s spouse Sallie Cole, born 1870, died 1942
I have copious data on these two people, including marriage date and place, exact birth date and place, exact death date, and place, and much, much more. But I just wanted to get the bare minimum into Ancestry to enable Ancestry hints.
There immediately were 15 hints for Alva Peters. I accepted the hint for the 1900 census. Doing so automatically created a Source for the 1900 census image, a Residence fact for 1900 with the Source attached, and an 1894 Marriage fact for the couple with the Source attached. They were really married in 1893 but the 1900 census reported that they had been married for 6 years. Ancestry did not add any information to the Birth fact for Alva Peters even though the 1900 census reported that he was born Oct 1870 in Tennessee which is more specific than I had typed into Ancestry. Alva’s name was not changed even though the 1900 census reported that his name was Alva E. Peters which is more information than I had typed in. Similar things happened for Sallie Cole’s Ancestry profile, but let’s just focus on Alva.
I used TreeShare to download the tree to a new RM9 database. I’m pretty sure using RM7 would have had the same results. Namely, TreeShare added a second Birth fact for Oct 1870 in Tennessee while also keeping the original Birth fact intact. The new birth fact has the 1900 Census as a Source and the original 1870 birth fact had no source. And there was an Alternate Name of Alva E. Peters with the 1900 census as a Source while leaving the original Alva Peters name in place.
So the TreeShare download added two new facts to the Alva Peters profile in RM even though the same two facts are not explicitly listed as facts in the Alva Peters profile on Ancestry. Therefore, TreeShare says that the two profiles differ in these added fact immediately after the original download. I suppose I could use TreeShare to push the two new facts back up to Ancestry, but I have not yet tried it so see what happens.
Is this an expected behavior that TreeShare will add facts and their sources as a part of the download that aren’t there in Ancestry? If I use TreeShare to compare RM and Ancestry after the download, I can see clearly that RM has the additional facts and Ancestry does not. I can also see directly in Ancestry that Ancestry does not have the additional facts.
