Early Massachusetts Vital Records 1600-1850 BMD
I believe this Massachusetts Vital Records Project was originally part of the US Genweb site for Essex Co, MA--or at least that is where I found it originally. Now it seems to be independent of US Genweb. The page is copyrighted by John Slaughter.
This is an excellent resource for anyone researching ancestors in Massachusetts!
Have a great day!
