I am getting closer to cracking this mystery... However I am struggling to find the evidence of births for Ann Simpson and her siblings. I did find Ann on the 1871 census in Sheffield also her brother Peter. They are listed as sister in law and brother in law. The head of the house is William Carter Marston and his wife is Rose Ann Marston nee Simpson.
I have all the siblings listed below as having parents John and Marguerett (Margaret Simpson) - However I cannot find out her maiden name.. I have a feeling the children were probably not even registered as Simpson. I cannot find a record for the marriage ofJohn and Margeruett either.
Rose Ann Simspon b 1845 (later marries David Marston)
Margaret simspon b 1848
John simpson b 1850
Joseph simpson b 1852
Peter Simspon b 1855 (on the 1871 census in Sheffield with his sister Annie)
Mary Simpson b 1856
ANNIE SIMPSON b 1857
James Simpson 1858
I think you may need to widen your search - I see that Rose Ann and the siblings living with her are all down as born Melton Mowbray in Leicestershire.
John and Margaret and their family are on the 1861 census living in Melton Mowbray
John Simpson B 1801 - Holme Yorkshire
Margaret - wife - B 1816 - City of York
Margaret - daughter - B 1848 - Stamford, Lincolnshire
John - son - B 1850 - Leicestershire
Joseph - son - 1852 - Melton, leicestershire
Peter - son - B 1854 - Melton, Leicestershire
Mary - daughter - B 1856 - Melton Leicestershire
James - son - B 1858 - Melton Leicestershire
Ann - daughter B 1860 - Melton Leicestershire
Might help you go back further with Margaret and John
Hi Sarah
I found the marriage on Ancestry. The references are in my previous post. Certificate can be purchased from GRO online as you probably know. Bear in mind the different spellings could be due to lack of literacy skills and accent.
Good luck
just an observation but betweeen the child born 1850 and the one born 1857 there was the marriage therefore was the marriage in 1853 a second marriage or is the marriage in 1853 not correct? I could be having a senior moment though.
