You can purchase the vol 2 typescript of the History of Alburgh from the Alburgh Historical Society. I have a copy and would be happy to do any look ups.
Stratton does not list Polly Babcock in the typescript. I found a Polly married to Ichabod on Family Search. Their daughter Polly b. 1805 married a McElvery she died in 1872 in Alburgh. Obviously not your Polly. I can look for any other Babcock info for you. I found another Polly Babcock mentioned in Volume ! of Stratton's Alburgh History. She married a man named Harry Emerson sometime in the late 18th century. Stratton does not mention who she was.
Have you tried the Babcock Family Genealogy by Stephen Babcock? That is where Stratton got his information on the Alburgh Babcocks. It's available on line through Archive.org. I did a quick search of the book and found nothing on your Polly.
