Hi,
The death that Irene mentions was in St Nicholas district, Aberdeen. He was 57 and mother's maiden name is on the index as Holmes.
There are two other John Snodgrass deaths between 1855 and 1861, their ages both unrecorded on the SP index; 1859 in Paisley (Low Church) and 1860 in Canongate, Edinburgh.
There is only one death in the SP OPR deaths for the name between the two dates and that relates to the same person as the Paisley d.c.
