Answer 2

In 1930 census,Coleman L. Beatty listed as Nephew is living with

Ellis Roussan in Granite City ,Madison Illinois.Now Ellis had a brother

David DeClue,It could be David DeClue was Coleman .L Beatty,father.

Julia DeClue had some children named DeClue and some named Rousin.

You should apply for Coleman Lester Beatty, birth record.But there is a

possibility he was born out of Wedlock.But it makes sense by going by

1930 census.
