OK I have finally found the birth record for a child who was born before his parents were married but noone picked up on this. No birth record could be found under his fathers surname so I went looking for his mothers maiden name and sure enough I found the birth record.
Trouble is that the child already has a profile with his fathers surname, but that was NOT his LNAB.
This is the profile in question - see the research notes I posted today.

So how should this profile be changed?
LNAB - Wadsworth,
Current surname - Connell
I have no idea if any formal official adoption was done or if this was all unofficial.
Thank you.
