Hello MarMnkly
Taken from the LDS 1851 transcript for Devon,
Mary Ann Shere age 47, Farmer's wife, born Cullompton Devon. Living at Yeates, Cullompton Tiverton
PRO Ref:HO/107/1888 fo225 page 14 FHL Film: 0221038
Ambrose was 52.
There is another Ambrose Shere on the transcript, age 26, unmarried, also a farmer in "part of Bradfield Barton," born Kentisbeare. I would think he must be connected. Ref HO107/1888 fo 424 p 17.
Hope that helps.
Nell
