Hi Obbie,
This photo was taken on 23rd September 1925.The bride and groom are,Michael Carroll and Elizabeth Herbert.The Man to the left of the groom with arms folded maybe Albert Brock,I don't know this,I'm just quessing.
The Lady to the left of him sitting is Louisa Doyle.Child beside her is Kathleen,and the other child is the surviving twin of Louisa and Patrick Doyle.The couple on the right is a mystery.I thought it may have been Parents of Louisa and Elizabeth,but their Mother died in 1910,I found out yesterday,have been to the births,marriages and deaths looking for info.
I don't know if you have a picture of Albert that you can compare.Sadly there is no one left alive to ask.
Hope this is helpful and if I get any more info I will forward it to you.
Regards Susan.
