This is what I have gathered from other researchers, and it may or may not be 100% correct. But here it is:
I have also seen Alida Louise Miller called Mary Alida Miller. She was born August 14, 1850 in Kaplan, Vermilion Parish, died May 23, 1951 in Grand Chenier, Vermillion Parish, Louisiana. She is buried in the Pecan Island Public Cemetery. I have the older version of the transcribed Cemetery and she is on it.
Her father was Joseph Ozachare/Ozencourt Miller (b. December 15, 1830 in Opelousas, Louisiana d. April 08, 1864 in Mansfield, Louisiana of war wounds from fighting in the Civil War). Her mother was Marie Delphino/Delphine Fruge
(b. September 20, 1835 in Opelousas, Louisiana d. August 23, 1853 in Opelousas Louisiana. However, it has been said that Alida's mother died when she was 9 days old, so this date doesn't check out, but it's what's available.). I do not believe that she had any siblings because her mother and father didn't really live long enough to have any and I haven't found any evidence that they had any more children.
If you want it, I have found an article about Alida Miller Broussard's 100th birthday, it's just a little large to post. It has information about her family and upbringing and how she met her husband. She is my g-g-g-grandmother.
I hope this helps.
