Hi guys
I am pretty desperate don't know which way to go. I have spent forever looking for My great great grandparents marriage their names are John Bowen b1842 and Mary Brookes b1845 as far as I know
They where born in Birmingham I think as stated on census
what I know
The first time either appear on a census is 1871 in Bangor Wales RG10; Piece: 5728; Folio: 4; Page: 2; GSU roll: 895818
Their first child Bertha Bowen was born in derby 1864 mothers maiden name Brooks
They lived in Dublin, Ireland we're their second child John was born in 1866
Two children born in Bangor Wales
The other children were born in Birmingham

John died Birmingham in 1909 and Mary in 1921
1911 census says married for 47 years RG14; Piece: 18063
I have not been able to go back any further as I don't know fathers names
Just feel like giving up
