I have found a Sarah Lock that died 7th October 1823 in Gloucestershire. Could his mum still have been a Sarah, just not Peters? I noticed a lot of people had Sarah Peters on their trees too so not sure where she has come from 😊
Yes, I think that is Sarah Lock née Peters, widow of Henry Lock of South Cerney who died in 1811.
This couple are not the Romani Henry & Sarah Lock. Someone made a wrong assumption and others have copied it without checking and researching further.
Our Sarah died in 1802 in Chetwynd, Shropshire. "Sarah, wife of Henry Lock, a traveller"
This is not far from Madeley where their daughter Lavinia was baptised in 1799.
I can't post the whole page as the file is too big, but it does say Chetwynd at the top.
