I have been unable to find much info on my 2nd great-grandfather that allows me to trace back further. What I do know is that he was born around 1884 (Possibly 31 March) in Northampton, Massachusetts. Later in his life, he moved to New York. He had a son, also named Daniel Griffin (1916-2003). His wife, Isabel Conway, predeceased him, and for a time, his mother and sister-in-law, Eliza Jane Conway and Marian Conway, also lived with him. Any help, especially in identifying his parents, would be greatly appreciated. Thank you!
