Thanks all for your help, much appreciated!
Just an update, I have found the death records for Jessie, David and William Templeton - all with parents Samuel and Catherine. I have been unable to find brother John's death record and Samuel senior's as yet. Mother Catherine appears to have died 1851-1854, unsure as to where. David and William died in Ayrshire and Jessie in Glasgow. It states on Jessie's record that she was buried in Troon. Maybe the rest of the family are buried there too. Any help with Troon MI's would be much appreciated.
Thanks
Caroline
