My Great-grandma was Ethel Emily Quarm, and she was descended from John Quarm 1746-1801 of Plymouth and Sarah Murch.
How far back have you managed to get on your line? Do you know who James Henry's parents were? I found his birth reg on the index, but couldn't find him as a child. Also I have a Henry Quarm on my tree, for who I cannot find a birth, or a death, and who disappears from the census when James Henry appears. I was going to get James and Emily's marriage cert to see if they were one and the same, but you may be able to save me £7!
I hadn't realised that Maud was James Henry's daughter, as she wasn't on the census returns I had looked at.
