Hi Heywood thanks for your input.
I am still to be convinced that the two records in question refer to the same person.
Firstly my reasoning is as follows:
Edward was born illegitimate and his surname was registered as Monaghan on his birth cert. For his mother, Ann, to have changed it to Goulden in 1871, and by 1881 to have changed it back to Monaghan seems unlikely. At the age of 11 Edward seems too young to have insisted on the change.
Secondly there are some additional facts. When Edward signed up to the army in 1886, he gave his next of kin as Ann Goulding, Ashton under Lyne. When he married Sarah Darcy in Dublin in 1890, on the marriage cert, he gave his father's name as Edward Monaghan (deceased).
As he married in a Catholic church in Ireland was he reluctant to admit to the priest or possibly his wife's parents, that he was illegitimate. So he made up a name and declaring he had died explained his absence at the wedding.
Alternatively i wondered if Edward (and wife) had adopted Edward at birth or soon after. This was why I was searching for him in the 1871 census records. The records for Ann Goulden don't support this.
Things aren't helped by a 1901 Census record from Whittington, Staffordshire.
While Edward was serving in South Africa in the Boer war, his wife Sarah (Darcy) was at the Regimental barracks with all her children,
Sarah Monaghan 37 Head
John Monaghan 7
William Monaghan 5
Alfred Monaghan 3
Kathleen Monaghan 1
Susan MORAGHAN 51 Mother-in-law.
RG 13 Piece 2656 Folio 174 Page 19.
So did Sarah assume Susan was Edward's mother or did she know about Ann Monaghan?
Was Susan, Edward (senior's) wife, or did Edward make up the name on his marriage cert to avoid embarrassment. What a family.
Now you see why I am asking for help.
