I am
assuming that William Ignace Gibson was the composer that went by Ignace Gibson
e (1826 -1897)?
A mini biography of Ignace Gibsone lists James and Ann as his parents, but I have no idea of where they got that info:
https://musicalics.com/en/node/98594Other sites that Google showed lists Ignace as of Scottish and French heritage. If I have been tracking James correctly, he is Scottish, so that leaves Ann as possibly French. Could they have married in Scotland?
Again, if I am chasing the right fellow, James is alone in 1841 census, musician, living in Maidstone, but by 1851, he is with a new wife Elizabeth, and several children, oldest being 17. I can't find her and the children in 1841 so far.
It seems this James died in 1860, and there is an article on his death, which gives no family mention, but talks a bit about his music. If you think I'm on the right track, I'll write out the article.
EDIT Ignore the 1841 census mentioned in this post. Please see Reply #8 by Trish1120 for the correct one.
