Further to this, in 1861 Elizabeth Corkill is 14 b Onchan at Ballakewish House, Braddan with her parents and siblings including a married sister Margaret Cowin, husband Rob't Cowin and 4mo baby Margaret.

In 1871 at 22 Drumgold St, Douglas, are the parents William 64 Retired Farmer b Lezayre and Margaret 62 b Onchan. All children now gone.

In 1881 at same address are William 74 Butcher b Douglas, Margaret 71 b Douglas and Elizabeth Cowley granddaughter age 5 b Douglas. I think this confirms Sue has the correct marriage for the daughter Elizabeth.
