Thanks Merry. I entered the street name and street and it worked, even without a town. It gave me 4 different towns to choose from.
Neither person was at the address they said they lived at on the marriage register. However I don't understand why they lived somewhere (assumedly separately) on the 1861 census then both moved to separate addresses for when they got married. As they were both over 70 would anyone have cared if they were living together?
I thought I was so clever using the marriage address to find my lady.
