Austens, Browns, Hubbacks, Leighs & Gardeners

Following about 15 years research I still cannot fathom the Hubback line. Any help would be very much appreciated. It is known that the two brothers of my great great grandfather (John Henry Hubback went to America. It is believed that one of them had a son (Edward?) and a daughter (Claire who married ? Sage). but there we draw a line.
The Austen and Leigh lines were much easier to research as my 4 greats grandfather was brother to the authoress Jane Austen.
Gardeners and Elwoods are even harder than the Hubbacks as they are from India. It is known that we are related to Lord Gardner of Uttoxeter, but how?
Other lines of interest are:
Boschetti (Fanny Frazer Newberry d of John)
de Rozario or Rozario
Clay
Ingram
Clavell (of Dorset)
