He lives with his parents in the 1910 and 1920 Census, but there is no obvious candidate to be him in 1930. For now, I lose all track of him.

There is a Frederick D Snyder age 29 born in PA married in about 1923 living in Qunicy, MA. He is an electrical engineer with Westinghouse. His wife is Marie L age 27 born in Missouri and they have a son Daniel E age 3. I have no idea if this is the right Frederick D so have not added his wife or son into my database.
