Debushe Family History & Genealogy

According to 1920 census my grandfather, Buford Leroy DeBushe, his wife, Esther, and their two daughters, Yvonne (my Aunt), and Valeta (my mother) were living on East 8th Ave. in Gary, IN. I think he was working as a clerk in a haberdashers.
He must have come into some money because by 1923 he had a 40 acre silver fox breeding ranch in full operation. He was apparently in partnership with a man named Nicholson. I have an advertising booklet with photos from the business as well as many photos of the ranch itself and the foxes.
The fox ranch was situated at 45th and Cleveland in Gary, IN. Specific addresses for his business were: DeBushe-Nicholson Silver Fox Co., Route A, Box 169A or 179A, Gary, IN or All American Silver Fox Co., 109 N. Dearborn Street, Suite 603, Chicago, IL. He was listed in Dunn and Bradstreet.
Something went wrong in 1927. This is the year my mother says he left and "everything, even the furniture, was auctioned off." Don't know where he went. Don't know what happened to Nicholson. Family anecdotes indicate there may have been some kind of fraud. The rest of the family (Esther, Yvonne and Valeta) went to relatives in Denver and later to Elgin, IL. Esther never went back to him, although I don't think she ever divorced him either.
One family story is that he went to Joliet and turned himself in to avoid the people to whom he owed money. The inference is that it was "the Mob." The Illinois State Prison System says they have no record of him. My mother told me a long time ago that he did know some of the "Mob" people, possibly Al Capone. This may have been one of her "it's not exactly true, but it makes a good story" anecdotes.
DeBushe turns up again in Soap Lake, WA in 1935. According to his obituary he ran a rheumatism clinic for 6 years there before he died September 6, 1941. I have a photo of him in front of his business with his name painted on the window behind him.
On an audiotape my mother she says he spoke French, German, English, Italian and Yiddish. He was a left-handed golfer, but two letters written by him in 1938 show he was a right-handed writer and quite fluent in English. Mama says he was well educated.
I have a photo showing him with 2 younger brothers (Dana and Franklin?) and 3 younger sisters (?, Velma, ?), a photo of Velma in Seward, Alaska taken July 12, 1912, and a photo of a man with my mother and her sister taken in the 20s labeled in my grandmother's handwriting "Dana, Leroy's brother, Yvonne and Valeta." The photo of him with his siblings may have been taken in Marseilles, France, where he was born.
It would be really interesting to find out where he was between 1927-1935 and where his parents, Benjamin Alfred DeBushe and Mercedese De Carvour came from.
