= Edwin Fitch Northrup = Keith, Here is what I can tell you so far. It appears he had no children. In the 1900 census he is single, occupation Electrical Engineer and living in Baltimore. In the 1910 he is married 9 years and has had no children. The 1920 and 1930 censuses also show no signs of children. I think his estate will depend on a will, which I don't have easy access to. Below is a an article I found on him in a Syracuse newspaper, and the information from the censuses. Bill .
