Hello,Chris. I do not know if you have this information or not.But I will send it anyway.
"Vital Records of Mendon, Massachusetts" To the Year 1950.Complied by Thomas W. Baldwin, 1920.
1. David of Douglas, and Phebe Trask, int. Nov.17, 1763.
Does not list any dates of birth & death of your David.
If you can find this book, it will be a great help.It covers the births, marriages and deaths of quite a few Aldrich's.My wife is an Aldrich, born in Maine.I have the 6 volume set of the Aldrich Family by A. Aldrich.Its full of errors, but it points you in the right direction.Will check there and get back to you. From another Chris, have a good week-end and a safe one. Chris
