Yes we are certainly related through George & Harriet. Regret that I haven't really researched this part of the family in any depth but am in touch with distant "cousins" in the States.
You probably have most of the following but just in case I send what I have.
George William & Harriets children Mary bapt. 9th November 1851 George bapt. 24th September 1854 Christopher John born 3rd September 1856 bapt. 28th Sept. Ada bapt. 7th November 1858 Arthur bapt. 17th February 1861 Joseph bapt. 15th March 1863 Sorry I have no info. on the above except for------
Christopher John married Mary Jane Allott (my Gt.Grand Aunt) 22nd December 1881 in Hull. Christopher is listed as an iron founder and pawn broker, living in Chapel Lane, Hull
Their family: Christopher John born 1885
Mary Jane born 10th April 1883 married John Henry Woodward On Johns death she married a Mr. Renfro. Mary died in Placer,California 10th October, 1961. I am in touch with some of Johns family, in fact just received a message from Virginia his gt. grand daughter yesterday !!
Harriet married Mr. Bailey
Nena born 7th June 1886 married John Firth in Hull She died in Los Angeles 24 November 1969. Again I am in touch with some of John family.
Hope the above is of interest. If there is anything else you need I'll check deeper.
