Hi Pauline, I am just starting to research my grandmothers family tree. Her maiden name was Gladys Ackerman and she came from Mitcham which was where my mum was born. So you never know we could be related. I know that the family moved there from Bridport in Dorset a couple of generations before she was born I would love to know any information you have and I am willing to share any info I have with you I have loads of Ackerman's born before the 1900s but from there it is a little sketchy. I think my g grandfather was stephen and his father was Abraham. In the 1881 census There is a david ackerman in Mitcham the david you are looking for may have come from him let me know if you want me to share all the info I haveChristine.
