Apologies, as I've stated on the other thread I was trying to separate out different parts of Joseph's life and clearly not done so as well as I'd hoped.
Perhaps the mods could merge the threads? (Is that possible?)
That notwithstanding, thank you all for all your input so far! You've come up with a lot of suggestions and not all overlapped! I'll try to answer a few queries that have cropped up:
I have no proof that my Joseph was actually married to Mary. I've never found a marriage for them. But let's call them married, for the sake of brevity. They are named as the parents on the baptisms of all the children I've mentioned between 1812-1827. (One Joseph Langton had banns read in 1810 to a different woman, but the banns note that the marriage was not allowed by the bride's mother! So maybe Joseph decided not to bother a second time!)
There are errors on some certificates, maybe errors on the censuses (thanks for spotting "Thomas" in 1851!) and I've only been able to make some of the links through other means, eg. witnesses at weddings and shared graves.
That notwithstanding:
1835 - wedding between "Louisa" Langton and William Wakelin -- the certificate is currently refusing to load on the comp but I've seen it before, father confirmed Joseph Langton and something to do with hosiery making (weren't they all in Leicester!!). Not stated as deceased.
1841 - John Langton m Mary Wade -- father Joseph Langton, FWK. Witnesses Thomas and Mary Ann Kilner (the Kilner wedding was witnessed by John Langton and Mary Wade earlier that year).
1846 - Elizabeth Langton m John Jeayes --- and Elizabeth's father shown as Joseph Jeayes, FWK!! I am 100% convinced this was an admin error. Witnesses John Langton and Eliza Wakeling.
1871 - Eliza Wakeling, widow, married Isaac Glover. Father Joseph Langton, FWK.
(and inbetween, Eliza lived as "wife" to Thomas Kilner when he was widowed, Thomas Kilner's son married Elizabeth Langton/Jeayes daughter, Elizabeth Jeayes' death cert gives the wrong name, and several members of the Langton and Kilner families share a grave. Confusing to try to explain but it helped to pinpoint people).
As someone has already said, one Samuel Langton was witness to the marraige of Joseph Langton and Elizabeth Peters in 1831. The certificate doesn't state whether either groom or bride was single or widowed. I don't know Samuel - he was part of the question I was trying to pose on the other thread.
Joseph's daughter Elizabeth (who married Jeayes) is my ancestor and I can't find her in 1841, unless that is her in the Langton/Peters household.
I can't identify "Edward" in the 1841 census. Joseph baptised a son William in 1827 and I can't track him after this, so I thought it could be him with a name change. But Edward Langton appears in subsequent censuses married to Mary Ann --- and the possible marriage (1844, Mary Ann Gray) gives Edward's father as William Langton.
Can I prove or disprove that the Joseph Langton who was father of Eliza, Elizabeth, John (and others) is the same one as he who married Elizabeth Peters and had more children? Of note, none of the childrens' names across the two marriages are duplicated.
You can see why this is driving my nuts and I'm sorry if it's done the same to anyone else!
