Have you already searched the UK census records for Mary Ann Dando?
You may have already seen this transcription of an 1881 household on the LDS website (http://www.familysearch.com
Name Relation Marital Gender Age Birthplace
John PERRY Head M M 40 Clutton, Somerset, England
Mary Ann PERRY Wife M F 33 Clutton, Somerset, England John Herbert PERRY Son U Male 12 Clutton, Somerset, England Harriett Rose PERRY Daughter F 9 Clutton, Somerset, England William Aaron PERRY Son M 7 Clutton, Somerset, England Walter Frank PERRY Son M 3 Clutton, Somerset, England
If this is your ancestor Mary Ann and If Mary Ann was born in Farmborough, Birthplace should show that, not Clutton, but maybe the census taker got it wrong.
The 1871, 1861, 1851 census records for Clutton should help clarify. LDS doesn't have those.
