Hello Jacqui, Bryant, Minak.
Am really pleased to read your interest as Archibald and Mary Duprey were my Great Great Grand Parents and I too have had trouble finding a marriage. I found them through my Great Grandfather Frederick Duprey's birth certificate , born Rochford 1843. By 1866 he is in Reyleigh Essex and his marriage certificate to Matilda Lucy Holman gives his Father as Archibald Ambiland Duprey - Tallow chandler.
Archibald's death certificate shows him dying on 19th September 1844 at Rochfoerd, occupation Tallow chandler and cause of death scarlet fever 1 week. Registered 20th September 1844 by the mark of Sarah Salmon - in attendance.
The certificate for Sarah Salmon Duprey born 27 November 1844 at Rochford gives Father as Archibald Duprey (deceased) and Mother Mary who registered the birth on 4th December 1844. Census returns confirm Sarah Salmon as Grandmother for the child , but it seams that Mary had another marriage before Archibald.
A certificate for Alfred Duprey born 22 June 1841 , gives Archibald as Father and Mary formerly Banyard as Mother. This was registered by Archibald on 22 July 1841 and gives an address of 14 Old Street in the district of St Luke's Middlesex. This gives the answer to the 1841 census question as I have looked it up and it is one of the missing pages for that census. Typicall !
Being on Old Street links in to the St Luke's registers and the entry for an Archibald born to Francis and Elizabeth which I have taken as our Archie. Have wondered if the William in the 1841 census is Father to Francis and also where Mr Allen fits in.
Frederick remained in Rochford , recorded as a bootmaker and by 1881 had a shop in Prittlewell Southend. I too have not found him in 1871 , but a family story that he travelled in America has been borne out by an obituary report. Perhaps he was there then ? His son alfred , born 1869 , emigrated to Australia and I have copies of photographs of him in sidney. Frederick died in Southend in 1928
Still digesting all the bits of information and would love to share other information and ideas.
