I am trying to go further back in my tree than Ross H. Dinsmore, born in 1578 in Scotland. This is his direct, male lineage down to me:

The furthese back I can get in my tree is:
Ross H. Dinsmoor, b. 1578, Scotland.
son Laird Douglas Dinsmoor, b. 1598 Nova Scotia, Canada
son Laird Robert Dinsmoor, b. 1622
son John Dinsmoor, b. 1650, Scotland
son John Dunsmoor, b. 1670, Ireland
son William Dunsmoor, b. 1698, Ireland
son John Densmore, b. 1743, American Colony
son Reuben, Dinsmore, b. 1771, American Colony
son Charles Augustus Dinsmore, b. 1819, MA, USA
son George Augustus Dinsmore, b. 1861, USA
son Paul Horton Dinsmore, b. 1892, USA
son George Anson Dinsmore, b. 1924, NJ, USA (my father)
son Mark Palmer Dinsmore, b. 1952, CO, USA (my brother).

Can you offer any insight into Ross or why he might have been in Nova Scotia for the birth of his son Laird Douglas Dinsmoor?
