My wife Janet Glew is a member of this family and would like to exchange information with you but (un)fortunately we are going on holiday and she will not have time until we get back.
Her family history is shrouded in mystery, her grandmother (Sarah) was born in New Zealand in 1875. She has always understood that her ggrandfather was the George Glew which you have as being born in 1832. In 1901 Her grandmother was back in England living with Moses and Aaron.
The problem is that Jan's father was illigitimate and never ever spoke of his family, so she knows very little.
