This John is also interesting, he was bap. 1863, on the original it says abode Peterborough.. I also recognise one of the signatures for godparents, but can't place it yet.

Of course we are basing our searches on the fact that Ann/ie says she was a spinster, Zaccheus died 6 years after their marriage aged about 56y, so he was about 50y when he married her. Age gaps not unheard of but...
Ann was living in Dartmouth Hill, the next street to Zaccheus, when they married. If she had moved to the area to meet the banns criteria she would have probably given his address: Blackheath Hill, so it is probable that was her place of residence, yet no sign in the census.
I can't even find Richard George W b. 1870 in 1881.
