Hi JM,
Thank you for the link to George Anseline, showing his criminal history and photo which was interesting.
I actually found him on Trove, with newspaper reports in Evening News (Sydney) and also in Star (Sydney), 2 April, 1909, describing the alleged bigamy referred to.
In the Star, it states: 'George Anseline, or Francose, 27, a colored person from Mauritius, described as a greengrocer, charged..etc'
In the Evening News: 'An alleged bigamy case, in which accused and his father-in-law and other witnesses were natives of Mauritius...etc'
I have wondered where he fits in.
However, in 'Slave Registers of former British Colonial Dependencies, 1813-1834' (Ancestry), there are Anseline families who appear to have had slaves - one of the slave owners was a 'Francois Anseline' who died, however, around 1830. Subsequently, I believe slavery there was forbidden after the mid-1830's.
I would assume that it was not uncommon for slaves to take the name of their owner.
Although I don't have any photos of Jules Francois Anseline, photos of his offspring do not indicate the same features as in the photo of George.
So, quite possibly, George may have been an unrelated descendent.
Incidentally, I have looked on the National Archives of Mauritius website which, I think, you sent me, but it seems to be fairly 'embryonic' - they say that they're still uploading their records.
