Hi Kerry,
That was an important find, how sad it would have been for his real mum

if you hadn't spotted it.
Same problem here with my G grandmother, my grandfather just made the census at seven months.
His father wasn't on the 1901 census but his mother is listed as married not widowed....waiting for certificates to get his dads name now
She re-married within six years, I know of another child whom so far I haven't been able to trace, so yes, second marriages are just as important .
As you say... roll on 2011.
