Curtis. Sorry this reply took so long. I stopped getting message alerts when someone replied to my query. All of a sudden they started up again. I see there are a lot of replies. Yes there is a relationship to all.
Edward Andrew LeBeau was the son of John B. LeBeau and Henry A LeBeau was the son of Peter LeBeau, so they were cousins (John and Peter were sons of Antoine LeBeau, Sr. and Mary Makes Mouth (Little Thunder)
Henry's 1st wife was Lucy Swimmer b. 1891, d. 1911 and their 2 kids were Richard (1909)and Adelia (1910)
#2 was Rose Hopkins, and I show 5 children Lloyd A. b 1915; Homer J. b. 1916; Zelda b 1921, Willie B, b. 1917 and d. 1920; and Alma b/ 1924 and d. 1934. #3 Gertrude Laundreau Robertson M. 9-29-41. she died in 1978 and Henry died in 1982. Andrew LeBeau was Henry's 1/2 brother. Andrew's mother was from Peter's marriage to Virginia Jennie Ducheneaux (she had 8 children with W. Ducheneaux who died in 1911) How are the LeBeau's related to you?
