Hi,
BIG SORRY I typed the wrong year for marriage it should have been 1835. It is your John
1851 Census he was living with his inlaws, with his wife and children.
You can see this marriage by searching
www.familysearch.org.
There is also a marriage 31.12.1812 Ilkeston German Buxton = Elizabeth Henshaw.
I have only found 1 chid Bpt to them
Weslyn Meth. Ilkeston
Born 2.9.1816 Bpt 30.12.1822 Elizabeth Parents German Buxton Elizabeth Henshaw
Think these may be the parents to your John - but need to find evidence.
Hope I have no typos this time.
Spendlove
