Thank you so much for the speedy replies.

I'll try and keep it straightforward.
I have an Elizabeth Ann Hessey baptised Catholic (her own parents however had 'special dispensation' to marry in the Catholic Church, appearing to be 'mixed religion and her 6 months pregnant...) Anyway. She married Thomas Parkinson (baptised CoE) in 1915 in a CoE Church over the other side of the city. She is 3 months pregnant.They give their ages as 19 and Thomas 23. In actual fact, birth records show they are 18 and 27. (Parents must have known as she would have needed parental permission wouldn't she?)
The first baby is born 6 months later, then 2 more follow. All baptised at St Malachy's Catholic Church - right near where they live, when... in 1921 they appear to marry again at.. St Malachy's

!!!! Surely a Catholic Church wouldn't have allowed the baptism of their children if they had married CoE?
I am so puzzled. I have checked and checked my records, parent details, witnesses, addresses, occupations, subsequent children - even as far as the 1939 register to see if there was , by chance, another Elizabeth Ann Hessey and Thomas Parkinson! So far, though there were another 2 EA Hessey's born within 10 years in Liverpool, the maiden name of the children rule them both out and one would have only been about 9 I think to have married in 1915!!
I am at a loss to try and even consider what may have gone on here!
