Quite a few years ago, I submitted my Family Tree to the LDS site. Everything went through okay, and I was noted as the source of the information.
During recent searches of the LDS site, I've noticed some changes with some of my original Family Tree members which I submitted those years ago. And whereas I was previously listed as the source of the information, it now indicates no source.
There have been quite a few of these "amendments" I have discovered, and I just had a quick look at LDS site to give you an example;
I originally gave the information to the birth of one ancestor as "Salisbury, Wiltshire". It now appears as "Salesbury, Lancashire"! I'm not listed as the source as I was originally. Another has mistakenly given the birthplace of my grandmother to my grandfather, her place of birth now being where she was married!
Yes, be careful of the LDS site. Somebody(?) does update records, albiet incorrectly. Though to be fair, I have obtained a lot of invaluable information from the site, most of it correct (I think?).
