I am currently researching my section of the Sussex Boys family. My grandfather was Charles Edwin Boys born in Southease in 1885 and married to Ada Maria Hilborn in 1912 in Ringmer. First child (of nine) was Marjorie May Boyes - note the addition of the 'e'. They moved to Woodmansterne, Surrey, then Woking but we also have huge links with Ditchling and have Boys ancestors buried in the churchyard (gravestone still there). There are now lots of Boyes living in Surrey, originally BOYS but for some reason my grandfather added the 'E'. Not sure if your branch is related but I think I have just found my great grandfather, Charles Boys who in the 1901 census was living in the Newhaven area (Southease).
