Thanks, Shelley.  Yes, I've got these people sketched out on a tree, but just can't get any further.  I think I may have exhausted the on-line records now, as the wonderful Rootschatters would have found something new by now.  
Thanks to you, and all those who have contributed to my search efforts - this forum is just amazing, the way it has people all over the world chatting and helping each other out.  
I still have hope in tracing Philip back through his father George Henry Taylor, born 1887 in North Tawton - he is the connection with our ancestry which I am so keen to tidy up.  Philip and his daughter's lives are a fascinating part of the story, but until I can formally prove their connection, I will have to keep delving away.  
Thanks again,
Meredith
