Dear Eric
I am a direct descendant of Robert Raisbeck Gelling and can provide you with a family history to the present day. His son John (my grandfather, survived the First World War and my father is Neville Anthony Raisbeck Gelling (still alive). He and his sister Una have compiled a short family tree and family history, which I would be happy to share with you. We lost the Raisbeck after my father's generation and so my brother is known simply as Arthur Gelling.
Best wishes
Rowena Millar (nee Gelling)
