According to the IGI, a Catherine Kneen married a Thomas Templeton in Rushen
Parish 13 December 1855.

I couldn't find either a Catherine Templeton or a Thomas Templeton in the
burial index for the Isle of Man and I couldn't find one in the 1881 census index
for either Great Britain or the Isle of Man and I couldn't find any likely
Templeton offspring in the Manx IGI and they wouldn't likely be in the
British because Civil Registration started by then and that can't be
searched so comprehensively online.

I understand one of their offspring might be Agnes Templeton but this couple has evaporated on me. Can anyone shed any light as to what became of them? If this Catherine Templeton is who I think she is, namely the daughter of Eleanor Kermode and Richard Kneen, then she was Christened at Kk Rushen September 16, 1827.
