Hi
Civil registration began 1st July 1837. From then on father's names and occupations were required on the new format of marriage registers. Between 1754 and 1st July 1837 marriage registers had a different format which required the name and status (bachelor, spinster etc) of those marrying, their parish of residency for the last three weeks, whether the marriage was by banns or licence, their signatures and two witnesses signatures. If they were under age (below 21) and admitted it, then the register should also state they were a minor.
Unless a parish register gives a date of birth and the earlier the record is the less likely that will be, there is no birth record before civil registration only baptismal dates. The baptism in 1833 was indexed on the Family Search website which usually includes a birthdate in the index if one was written in the register. Westminster Archives hold the parish registers for St Clement Danes. Westminster Archives parish registers are being digitalised and placed on the website Find My Past.
Jennifer in her post of 22nd September transcribed a possible marriage entry for Samuel's parents James and Charlotte in 1812 at St Dunstan's Stepney. Both were of the hamlet of Mile End Old Town and were bachelor and spinster. The marriage was by banns. Jennifer included in her post all the other information found in the register except the name of the vicar.
Except for parishes in Westminster in Middlesex and some other individual exceptions the London Metropolitan Archives holds the parish registers of the those parishes in the county of London when it was formed in 1889 as well as the parish registers for the remaining part of the county of Middlesex which eventually became part of Greater London in 1965. The parish registers deposited at the LMA have been digitalised on the Ancestry website.
