Hi Pete,
As far as I can tell they were not related (his tree is on FS).
Maybe you could try finding more about Major John Rippingall who was a descendant of Henry Rippingall, attorney of Aylsham?
All I could find about him so far is that he was a farmer in Essex around the time he died, between 1993 - 2012. He was with the Kings African Rifles in 1945-6.

RIPPINGALL, GRANVILLE JOHN F T 1926

EDIT:
I have built a tree on FS and it turns out that Major Rippingall (Granville John Florance Thomas Ripingall) was the great great grandson of Rev S. F. Rippingall (Stephen Frost Rippingall). Another source says he died in 2009.

I still have to find a link between S. F.'s great grandfather Thomas Rippingall who married Elizabeth Worship in 1730 (Norwich and Fakenham records) and Henry Rippingall. I couldn't find Thomas Rippingall's birth record (around 1700).
