Hi Graeme dug out some more information which may be of help
Born around 1847 
He was 'reputedly' married to Mary Clark
Daughter named Mary Clark/Lumsden born c1868-1907
No info on any of his parents  
   
IGI gives a Richard Lumsden  born 1847 to Charles Lumsden & Elizabeth Bell Inverkething
but it look like this Richard married Jane McLaren 23.9.1870 Dunfermline
