Sorry it has taken so long to reply. I replied immediately to the list instead of the message board.
I have Sophia ESSEX born 25th Sept 1858 at Harborough, Leics
her parents were: William Levi ESSEX born 15th Oct 1815 at Canterbury, Kent.Died 4th Dec 1876 at Great Bowden, Leics
Esther SEAL born 6th May 1820 at Little Bowden, Northants.They were married at the Parochial Chapel, Market Harborough, Leicester, on March 8th 1840.Both made their mark in register.Witnesses Luke Fellows and Ann Richardson.

I think that the parents of William Levi ESSEX were:Levi born c.1778 at Coventry, Warwicks. and unknown Elizabeth. I think that Elizabeth died and Levi then married Ann WESTBROOK.

I think that the parents of Levi were: William ESSEX and Elisabeth CLAY. They were married 11th July 1774 at Wolvey, Warwicks.

I had not come across your Elizabeth born 1850, until now.
I have ; Edward 1852; James 1854;George 1856;Sophia born 1858; Ann born 1860. Of course as William and Esther were married in 1840 it is reasonable to think that they had some children before Edward. I need to look for the family in the 1841 census and onwards.

Does this fit in with your tree?

Kind regards,
Linda
