Hi Rosemary
Yes, there's lots of information about this couple. We have a photo of Rose Hill Cottage (their home in 1871) and one of their headstone in New Braddan Graveyard.
Robert Clague b 1816, stone mason, was a brother of my g g grandfather, William Clague / Clegg bap 17th Aug 1819 Onchan, bricklayer and builder.
Their father was Thomas Clague, also a stone mason, and their mother was Eleanor Gelling bap 9th Sept 1787 Marown.
Robert's wife, Catherine Clague b 1815 Rushen, was a daughter of Robert Clague and Isabella Cregeen.
Which of Robert and Catherine's children was your ancestor ?
Looking forward to learning more about your link to this family.
