Alfred Allen Eldridge was baptised at Battle parish church on 6 April 1856, son of Emery Eldridge and Emily (maiden name Wood). Emery and Emily married at Battle parish church on 9 September 1843.
Emery Eldridge was baptised at Battle on 22 December 1822, son of Thomas Eldridge and Elizabeth (maiden name not known).
My gr gr grandfather is Samuel Eldridge (bap Battle 22 February 1790), brother of your Thomas Eldridge (bap Battle 10 March 1780). They were sons of William Eldridge and Sarah Potter.
So, we’re distant cousins!
I have lots of info on Eldridges at Battle so happy to help further.
