The 1920 Census shows a son named Otto in the family. Was this really Adolph?

MARRIAGE:
Never married.

Several deeds mention Adolph, single, and Natalie G. Kapusta (and/or Kapustua), also single. She was born 28 Oct 1908. She died in January, 1977 but I can't find an obituary for her. Louis Kapusta was the executor of her will.

HEALTH:
Diabetes
