Welcome to RootsChat, dee1951

ADDED: Sorry GG, see you have posted the marriage details already!
Henry Harper Lomax married Marion Barret in Kensington, London in 2nd Qrt 1844 Vol 3/pg 208.
Is the daughter Marion the line you are descended from?
Birth 1840 4th Qrt - Marion Harcourt Barret Westminster - 1/ 102
From what I can see, the marriage did not fare well it seems. By 1846 they were in court due to his failure to provide for her. I think, from the way the case was reported at the time, Henry was very unbalanced/unsound of mind when he appeared in court. Commented by witnesses that this was a regular occurence. Not clear what the finals were on this.
Cannot see them together after this time.
He ended up in both a workhouse and also an asylum for some time. He was found dead in 1861 in Wiltshire. His sister was able to identify him at the time. A short summary here
www.geni.com/people/Henry-Lomax/6000000036210234065 but original records are available to confirm these details which I have been looking at.
Marion went on to have a relationship with a James Fougere and son James born? James Fougere, a widower and tailor by trade showing on the 1851 census in London.
Did they both leave with the children after the 1851 census I wonder?
There is a possible daughter showing for them:
Catherine Julia Fougere
Birth 10 Oct 1852 Tasmania
Registration Place Westbury, Tasmania, Australia
Father James Fougere
Mother Marion Barret
Window for travel. More children followed Catherine.
