My ancestor, Charles Piddington (c.1806-1876) was my mother's maternal grandmother's paternal grandfather. He appears on census forms in the east end of London, 1841, 51, 61 and 71 as a carpenter married to Ann Hansom (marriage London November 1832). However he shows himself as born in Daventry. It looks as if he relocated from Daventry when in his late teens or early twenties.
In 1841 there were three Piddington families recorded in Daventry:
William P (b.c.1802), a baker with his wife and 6 children appear to have moved away after 1841. Samuel, P (b.c.1803) (your ancestor through his daughter Maria) a publican/innkeeper with family is recorded 1841 through to 1871. (His son Joseph fell on hard times and was in a workhouse in 1891 and 1901. By 1911 there were no Piddingtons at all recorded in Daventry.)
Most hopeful is Charles P (c.1789-1871), a carpenter in Daventry 1841, 51, 61 and 71 married to Sarah Gray at Badby 03.12.1818. The coincidence with my ancestor of first name and trade seems encouraging but Sarah would have been hardly 12 when my ancestor was born and although that was then a marriageable age for a girl the much later marriage date makes it unlikely, as does the existence of a son born c.1831 also named Charles. However it is not impossible that my ancestor was the product of an earlier marriage or relationship by Charles. (I do have on my tree examples where children of a second marriage are given the same names as those born from the first marriage - very confusing!)
A further possibility given the close cluster of birth years is that William (b.c.1802), Samuel (b.c.1803) and my ancestor Charles (b.c.1806) were brothers with parents unknown and that Charles (b.c.1789) was not related or related in some other way.
Are the parish records you have seen able to sort this out for me please? Very grateful for any clues.
