Hi Kerry,
I think your grt, grt, grandfather - William Freeman might be my grt, grt, grt grandfather. My William is listed in censuses (censi?) as being born in Bovingdon, Hertfordshire circa 1837 although I haven't yet found any baptism for him there. William married Hannah Joiner nee Fountain in Bovingdon in 1858. Hannah, the daughter of Peter Fountain, was born in Wendover, Bucks circa 1837.
William and Hannah had at least 8 children that I know of - Henry, James, Thomas, Maryann, Fred, Ernest, Alice, and Albert; also I believe Hannah had a son, George, by her first husband David Joiner.
If any of this sounds at all familiar, please get in touch.
