I agree with this...using Ancestry.com to search for ANY valuable genealogical data before the first US census (1790) is pointless. It just isn't there.
Unlike old B/M/D records, which can be generally bought by the genealogist from the respective State/County/City website or office...Deeds, Wills, and Probate records are VERY difficult to obtain personally. In some cases, you can get them from the LDS library, but most of the time you have to either Inter-Library-Loan them through your own state/local library (local ones might not even be equipped for microfilm reading), or you have to travel to the specific State Library itself to gain access to it all.
I will admit, though, that Wills and Probate records might be impossible for Ancestry.com to license, due to the sensitive nature of it all. Deeds might be possible, though.
Can anyone from Ancestry.com weigh in on this situation? I feel like there is noone with influence even checking these topics sometimes...
