hi both
nannyj beat me too it I did the same checks no birth s anywhere close to epping , but did find the bpt for harriett I missed and you need to make a correction as she was born either 20 26 or 28 [ can,t decipher the writing ] 1829 and bpt 15 feb 1829 sorry for missing that before , also regarding john james I checked the register 3 times around the date you give and he,s not in the all saints book either , did you take his birth from census data ? .
went through the marriage register 1754 1785 and found these 2
Samuel boon wed Elizabeth how 12 oct 1770 one of the witnesses was a john how !
and Thomas aley wed an Elizabeth how 27 april 1761
presume we have 2 families in epping .
