Hi
Do you have census information? In 1891, Henry Jnr whith parents Henry and Elizabeth are lodging at 47 Dawes St, Bolton with
James and Kate Gavan and two year old Annie.
I can get full details. I'm not sure what you're short of.
Best wishes
Emms.
PS Update:
There's A Henry O'Neill married by 1901 to Sarah, with baby Herbert, at 25, Hanson St Oldham,
age slightly out at 26, Sarah 32, but I can't see another entry that fits.
