There are some on-line trees for David and Charlotte but some of them are a bit suss I think.
I should have given the reference for Jane's baptism - it's on FamilySearch and also on
London, England, Births and Baptisms, 1813-1906 which has the image of the register.
At st Paul's Deptford,
baptised 15 August, 1853
Jane Charlotte Clement WALKER
Parents: David, mariner, and Charlotte
Abode: New Town
Charlotte's baptism is on FamilySearch as well as
London, England, Births and Baptisms, 1813-1906 which has the image of the register.
At St Paul's Deptford, Kent, Borough of Lewisham
Born 4 Nov 1920, Baptised: 2 May 1821
Charlotte Clementina CLEMENTParents: William, shipwright DY, Mary
Abode: Victory St.
DY would be short for DockYard
There are some other baptisms which may be siblings for Charlotte. It's difficult to separate them as some of the birthdates are too close together to be from the same parents.
I'm just going to list them with in birth order. All have father listed as William, sometimes with occupation "shipwright DY" which is what is given for Charlotte's father. Sometimes the mother is listed as "Mary" sometimes "Mary Ann". All with surname CLEMENT.
Margaret, born 7 August 1817, baptised 7 September 1817
Mother listed as 'Mary Ann', living at Victory St, father shipwright.
George Bingle, born 10 July 1821, baptised 1 August, 1821
Mother listed as 'Mary Ann', living at Victory St, father shipwright.
Harriett Jane, born 20 June 1822, baptised 23 July 1822.
Mother listed as 'Mary Ann', living at Victory St, father shipwright.
Laura Betsy, born 11 May 1825, baptised 12 June, 1825.
Mother listed as 'Mary Ann', living at Victory St, father shipwright.
It is the overlap for George Bingle CLEMENT and your Charlotte which is puzzling - George's mother is listed as 'Mary Ann' while Charlotte's is plain 'Mary'
There are 2 other baptisms at St Nicholas, Deptford, both with parents William and Mary CLEMENT, but this man is listed as a labourer, so I suspect they are not the same couple especially as one of the baptisms is a week after the baptism of Margaret in 1817.
What a blessing to have your Charlotte with two distinctive forenames!
Judith who is not sure if I've just muddied the waters.
