Married Dena Kroph, was a shoemaker.
Listed in Wayne Co, PA in 1910, as a laborer in a shoe shop. They are listed below her widowed mother, and have the two children living with them after 9 yrs of marriage. In 1920 had moved to Binghamton, NY where he worked as a cutter (42, PA) in a shoe shop. His son and daughter were both still living at home, with Marvin being a bookkeeper for a meat market.
In 1930, he was still in Binghamton, with daughter Vera; and his wife is listed as Christina (52, PA), first married at age 22, parents born in NY and PA - my guess is that she simply stopped using her nickname.
Was living in Binghamton, NY in 1934 at age 52 when his mother died.
Listed as a laborer (62, PA) in 1940, with his wife Dena (62, PA) and daughter Vera (32, PA).
