Can you give me his parents' names and your sources for his "1869" birth registration and his 1901/1902 death registration (i.e. at 32Y) to confirm your assumptions?
Note: John Sylvester Franks born June Quarter 1872 in district East Ward (Westmorland) was the son of Sylvester Franks (b abt 1849 Compton Martin, Somerset) and Elizabeth Amelia Baker (b abt 1847 Blaenavon, Monmouthshire) ...Their names are confirmed in the 1904 death notice I'd given previously. John was baptised at St Michael's, Appleby, Westmoreland on 04 AUG 1872.
His parents were married in district Clutton (Somerset) in 1871. Dad Sylvester seems to have died in 1879 in in district Newport (Monmouthshire). (It might be that John spent most of his life in Wales, but he wasn't born there.)
Eva May and Henry Edward are mentioned in the 1904 death notice.
