Looking at the ages of Catherine and Ellen it is possible that they are part of the family of John Moore and Catherine Gelling.
Of the nine children five are still at home in the 1881 census at Balladole Braddan, one died in 1863 one married to John Caine 1880 and two , Catherine and Sarah Ellen are missing.
Their mother Catherine died in 1877 age 49.

There is an age gap of 21 years between Catherine Gelling and John Moore which may indicate a second marriage.
