Carl, I received your e-mail concerning the year of birth of David Rollo. John Rollo and Elizabeth Thomson had 14 children. The only two that I have some details of are Peter Rollo whose birth was recorded as 5th (no month given) 1855. I know David was in fact born either in 1853 or 1854. Davids first marriage to Betsy Mclean was registered on 31st Dec 1873 and was aged 20.The 1891 census described david as aged 37, which would have made his date of birth as in 1854. You say Eliza was born in 1828 and John Thomson Rollo as being born in 1830. Ten other children were born to John Rollo and Elizabeth Thomson that I have no details about. The above info was supplied by the Scots Ancestry research society.
