I read about the names Shaw and Elliot and the Townland of Clough.
In the book Gravestone Inscriptions Vol. 9 County Down Baronies of Lecale and Kinelarty; compiled by R.S.J. Clarke
publised by The Ulster Historical Society 1972
Page 25 states:
Under Clough Non Subscribing Presbyterian Graveyard
SHAW /Laid flat in modern Shaw enclosure /. Errected by Hugh Shaw, Drumaroad. In memory of his daughter Jane who died 16th of June 1848 aged 8 years. Here lie the remains of the above Hugh Shaw who died 24th March 1860aged 77 years. Also his wife Margaret Shaw who died 22nd December 1893 aged 91 years.
You may also wish to consult Ros Davies County Down Family Research Site as I have found overlapping family information that affects families from Both County Down and Antrim.
Hopes this helps,
