Hi Phil,
Heres Sarah Lean on the 1861 census -
RG9/1351 Folio 17 Page 30
Maiden Well, Portland, Dorset
Sarah Ann Kingcombe married 25 Dressmaker Chester
Sarah Ann Lean daughter 7 Millbrook Cornwall
She's more difficult to trace on the 1871 census and this is the closest match. It looks like shes taken on her stepfathers name and all the places of birth have been put down as Revelstoke (her mums age is wrong too

-
RG10/2105 Folio 42 Page 10
Revelstoke, Devon
Henry ..llis Kingcombe 56 Fisherman Revelstoke
Sarah 57
Charles 21 Sailor
Sarah 17
Archibald William 14
(Sarahs age is right, right name for mum, surname Kingcombe right...... )
Marriage - Henry Ells? Kingcombe to Sarah Perring?? Kingcombe? December 1838 Stoke Damarel Devon Vol 9 Page 540
Regards,
Catherine
