Thanks for the reply!! I would be happy to help you tracing the Bowers line if possible.
I am not sure what direction you are looking in but I'll give you the information I have at present.
I am only "married" into Bowers!! My husband's name is Roland Geoffrey and he has a brother called Gary Llewellyn. Their parents are Geoffrey Bowers (born Halifax, England) and Yvonne Ailsa Bowers (born Simon's Town, South Africa). I am still in constant contact with my husband's Grandmother in Yorkshire, England and his cousins in England.
If this track seems similar to the one you intend taking, please contact me and I will furnish you with addresses and telephone numbers.
