Charlotteratzlaff....I have just now found my way back to these message boards and seen your reply for the first time. I can not send you message since I am not currently a paid member. I would love to talk to you about your family! Just recently I believe I may have made the link between Fred and William. I believe Fred was living with a great Aunt, Caroline Goodayle, when he was a child in England. I believe Caroline to be the sister to William Pankhurst and their parents to be William and Sarah. Other siblings would be John b.1822 , Henry b.1824, Emma b.1827, James b. 1831.
I don't know how much you have came across in the last 9 years. I will defiantly look into that George Pankhurst that you mentioned. At one point I have came across a marriage record for Fred which listed his father as George.
