To clarify.....
Mitchell Edward Lacillade (b. 6/20/1913) m. Elizabeth Vera Thompson (b. 5/2/1913 - d. 4/19/1998) and they had 4 children together (Francis Mitchell Lacillade b. dec. 4 1935, Rosaline Marie Lacillade b. feb 11 1938, Beulah Marguerite lacillade b. Nov 29 1944, and Lois Jean Lacillade b. Aug 23 1950).
Mitchell Edward Lacillade (b. Jun 20 1913) was (I believe) the second-oldest of 5 children - in addition to the siblings named in Dan's note, there was an older sister named Beaulah Margerite Lacillade b. August 21 1908.
Mitchell Edward Lacillade (b. June 20 1913) was the son of Edward Mitchell Lacillade (b. 1870, d. May 18 1954) and Martha (Emma) Bates.
Edward Mitchell Lacillade (b. 1870) was the 4th-oldest of the 5 children born to Mitchell (middle name Edward?) Lacillade and his second wife, who was named Mary Guyette (d. June 5, 1886).
The name of Mitchell Edward Lacillade's first wife was Elizabeth Hull (they had only one child together - Samuel Henry Lacillade, b. May 3 1863). But Samuel Henry was prolific - he had 13 children, one of whom was my grandfather (specifically his 6th child, Walter Mitchell Lacillade).
