Hi
I am unable to find a death record for John Swadling, baptised Bucks 3/10/1824.
In 1841 Census: Great Marlow, John shown as single.
1845: John married Sophia Hester in Bucks.
1851 Census: Great Marlow, John shown as married but at different address to Sophia.
1861 Census: Great Marlow, Sophia shown as married but John not found.
1871 Census: Earley, Berks, Sophia shown as widow, John not found.
I can find no death record for him between 1852 and 1871 on FreeReg, FindMyPast, Ancestry, Family Search, MyHeritage or the Genealogist.
And I can find no record of his departure from ports at London, Portsmouth or Liverpool.
Can anyone please suggest further avenues to follow? All advice gratefully accepted.
