I think my Gt Gt Gt Grandfather is John Howlett. My nan was Mabel Hocking (nee Parsons), who was the daughter of Florence Mabel Cook. I think Florence's mother was Margaret Fanny Howlett. I'm yet to get confirmation as I'm waiting for birth certificates to arrive, but I am going by another family tree I have seen which says this is the case.
If you have any more information I'd be really interested to hear it,
