I recently purchased the 2-volume set of Compendium of Early Mohawk Valley Families by Maryly B. Penrose. It is a wonderful source of information on hundreds of families in the 1700's and early 1800's, including births, baptisms, church info, marriages, etc.
I WILL DO LOOK-UPS if you contact me with your family name.
My family roots go back to Montgomery County and I was thrilled to find LOTS of info on them here. Mary Jane Elliott firstname.lastname@example.org
