Hi Richard,
I've done this one before, years ago I mean, but it was to find this person, ''David Bryce Tod'' & his Father, but mostly his Father. I have info: on my computer reference his son ''David'', the one your researching, so I'll give you what I have on him. I do hope it helps some.
In 1911, David resided with his wife, two sons and a boarder in the High Street, Aberlady. His son James was a Civil Engineer, the other son Robert a Draper and the boarder John a Political Secretary. David was a Hotel Proprietor, and aged 72, his wife Annie Guy aged 66.
If I remember correctly David died in Aberlady aged 80 and his wife died in Canongate, Edinburgh, aged 87.
I'm sure both were interred in Canongate Churchyard in Edinburgh together because when searching after another person, David Rizzo, who died 1566 Secretary to Mary Stuart's, I did see Memorial Stones for families named Tod, some quite difficult to read due to weather damage. This Churchyard is considerably old and many of the Memorial Stones are black from soot, due to the black smokey chimney's of long ago.
Hope this helps Richard......................................................Ron.
