Again,apologies if I am wrong,but the data from jaycey seems to imply to me
1861 4184 72 7
1871 5552 33 9
and an 1887 marriage in the Lampeter registration district as per the 1871 above.This Hannah Jones is given as born Llawenog(near Lampeter) on the 1871
and is not consistent with the birthplace of Hannah Richards on the later censuses.She is however the only Hannah Jones who marries a William Richards in the general area in the general time frame,which may be how it was arrived at?
jaycey-does the birth certificate for Susannah Sophia give the mother as Hannah Jones or Hannah,formerly Jones(or similar?)
