This whole scenario gets more bizarre by the minute - have looked at 3 different sites but cannot find Thomas, Ada and Horace in 1901!
However, I did find marriage of Edgar Horace Eldridge to Ada Lilian Longley in June qtr. 1897 Godstone, Surrey and a son William Henry Eldridge birth reg'd Mar.1902 Godstone - this is the son William with Ada in 1911 - neither Ada Lilian, son William or even Edgar Horace Eldridge were born in Coventry so why is this place being stated on census (for Selina too in 1901). Indeed, Selina Ann Longley and Ada Lilian Longley were sisters, mmn Meapham and were both born in Cowden, Kent. Edgar Horace Eldridge was born 1873 in Westfield, Sussex but by 1891 he and his family are in Warlingham, Surrey.
What is it with this family? If Ada Lilian Eldridge, nee Longley was indeed Thomas Stringers cousin, that means his later wife Selina was his cousin too??
