Thank you to all who replied.
Due to the mother's name being the same on both the 1920 MC and on Peter's DC, I came to the conclusion that there was an error on the 1920 MC
EV,
Re the 1911 census in EK
I found that same family in Barrhead at 1901 but, I was still unsure if this was the correct Carey family
I obtained the birth cert for the youngest son named as James Carey born 1900
Parents were:
Peter Carey and Elizabeth Black who married in Shotts, Lanarkshire in 1891.Unsurprisingly, I cant find the stated marriage or births of Richard and Peter!
--------------------
My other anomaly MC relates to my ggg grandfather who remarried in 1860.
Correct details are entered for my ancestral grandfather. ( widower, address and parents)
All subsequent children born to his 2nd marriage show the same marriage date ( in Glasgow) and name the same mother.
The MC doesn't make sense.
The spouse named on the cert ( first and last names) is completely different to his known wife, mother of his children.
The only thing that sort of matches is mother's maiden name for the bride listed on the cert
THIS is the exact name of my ancestor's 2nd wife and corresponds to the mother listed on the subsequent birth certs?
The biggest issue:
The MC states they married under the form of The Free Church Of Scotland ?
I do not believe that they had a Free Church Marriage
This family was Irish Catholic!
1st marriage and all children born from both were RC and all had RC marriages.
They are all buried in RC cemeteries?
Parent info on death cert of this 2nd wife bears no resemblance to those listed on the 1860 MC.
(Yes, her mother's maiden details differ from the 1860 MC)
I am 100% convinced that the registrar was having a very bad day when he filled out this 1860 MC
