I'm not researching this family but I was in Lauder cemeterary earlier this year and took photographs of various stones.
Amongst them are 3 Redpath family stones.
They may be of interest to you.
William b1868 and wife
James b1873, wife and sons George and Thomas
Robert b1909, wife and son Adam Robert. (Robert married a Forrest which is the name I was researching, hence my reason for photographing the other Redpath stones).
Let me know if you want more info and / or the photos.
