Found my relative Dorothy (AKA Sadie) Muller living next to her parents in Brooklyn, NY in the 1930 census. She is married to Nathan Ente who was born about 1902 in NY. It says they were married about 1920, and have 2 boys: Charles and Chester. Charles was born about 1920 in New Jersey.
Dorothy was named Sady E Barger and listed as a widow in 1/1920 in the 1920 census. So she must have already known Nathan. I don't know if Charles is Mr Barger's son or Nathan's. If anyone has any info on this family please let me know.
