Hello Liz
About twelve months too late but I have only just come accross you and as you may already have your answer. Going by the 1901 census your Poole Family were living in Poulton Gloucester and yes Edwin Rolfe was with his family .
Also did you know that Rose Poole died Reg. June 1920 6a 424 at the age of 39 Cirencester more than likely Poulton.
A Charles Poole died Reg. March 1961 Cirencester aged 82 and it looks like he is the right Charles.
William Poole 1845 as you know was the father of Charles Robert Poole 1879 and he married Jane Ann Morris but do you know who his parents were if not I can let you have that info also as Williams parents are my Grandparents, well at least the mother is.
Hope you find some good info out of what I have given you.
Your Possible 3 times Cousin once removed or pretty close anyway.
