Hi Shawna
My OH's connection is through Harriet Ruth Harper c1832 Blofield who married a John Thatcher at Wandsworth in 1859. The Wandsworth Thatchers are my personal FH nightmare

I am now not 100% sure which line my OH's G grandfather is descended from as there appears to have been at least one marriages of first cousins involved.

(Explains a lot about my OH but we won't go there!!)
I only know of Harriet's siblings from the census of Tovel & Ann's family. One of them was a George
Henry Harper born 1838. None of the baptisms appear on the IGI that I can see. Perhaps they became Non-conformist?
Tovel is buried at Blofield Dec 13, 1872
Anne Rushmore Harper Nov 7, 1886
I believe they were married at Lakenham Jan 26, 1829
