Robert Lamont who married Grace Burns in 1871 was my relative. and has no apparent connection to the family on this thread.
He was born in Lanarkshire in 1849 and his father was not called Robert.
He appears on every census in Lanarkshire with his own parents before his marriage and subsequently with his wife and children on every census until his death.
I hold copies of every document as proof.
The date that Trish posted, 14 Mar 1881 is actually the DOB for his son who was named Robert Smith Lamont.
This child was, in fact named for his own maternal grandfather.
All of my families, Lamont, Smith and all associated families hail from Cambuslang and have no obvious link to Robert Lamont and Isabella Gillespie Smith
