Heywood -- yes, it looks like they are part of James Albert's family -- the dates and locations seem right --
and I am gradually sifting methodically back through all the data I have been presented with to establish the fullest picture. Both families use similar names when children are born, causing some confusion when brothers and sisters have children of about the same ages with same names.
My major problem remaining is that you have discovered that Mary White Carpenter's father is Patrick whereas the Marrriage entry I recently obtained show Charlotte's father as Alfred – That is a dilema, Alfred v. Patrick.
December 4, 1901, the date of birth given on the several documents I have pertaining to James Albert Knighton, convince me that I have identified the right James Albert Knighton, my father who died November 7, 1929, several months before I was born.
I can also be sure of the names of the parents of James Albert Knighton because they are given on the baptism entries of the St. Michael Catholic Church, in Liverpool (or possibly West Derby – part of Liverpool). The matching birth date is given as December 4, 1901.
When baptised he appears to be living at 30 Cottenham Street.
His parents are noted as Charlotte, former surname White, and James Knighton.
And I have accounted for his siblings to a small deree
The baptism entry shows the godmother to be Mary Ellen Carpenter, Charlotte's sister and the aunt to James Albert as shown on 1911 census when she was taking care of James Albert and some of his siblings. Charlotte's sister became Mary Carpenter on her 1886 marrriage to William Carpenter.
Because of the differing brifes father's names, Alfred and Patrick, what I am not 100% sure about is that I have the right marriage certificate for James Albert's mother and father. The Entry of Marriage that I have is for Charlotte and James, it took place 22 July 1891 at St.Aidan's Catholic Church in West Derby. The ages are correct according to matching dates given elsewhere on census documents and the location also appears to be appropriate for the Knighton couple. And how likely is it that there would be two Knighton-White marriages – not very I'd say.
But there are other similarly aged Charlotte and Mary Whites – probably close relatives of our Charlotte and her sister Mary, living in the same parish, even on the same street and working in the same occupation.
