The only person on Ancestry.com I can find who has done research on the Stuarts of Birkenburn is username scseke and he has done great homework but his style leaves a lot to be desired. He cited as a source

The man I am trying to connect is Robert Stuart (1768/69-1852) who was an army pensioner who married late in life after his military travel was over. When he was 57/8, he married 28 yr old Christian Stuart of Tomintoul. They moved to Dufftown about 1836-38 and raised a family there. Robert died in Dufftown in 1852 and is buried just south at Mortlach. Banffshire. All census records have him born in Banffshire, with one census reporting Rothiemurchas, Banffshire as a birthplace. His marriage record in 1825 reports he is from Delliefure, Cromdale, Banffshire.
John Stuart of Birkenburn (1733-1822) had 4 sons with Helen Anderson - including Robert Stuart baptized at Keith on 8 Oct 1768. According to the poster on Ancestry.com, this Robert Stuart was last heard from in 1815 when he visited Birkenburn, and then he died unmarried.
Could this be the same person? The patronymic naming pattern is present. The birth year is close (all we have is census ages for the Robert Stuart in Dufftown). Both went into the Army.
Coincidental,yes. Still after doing this for so many decades, my nose is smelling something worth researching further. Do you have access to military records by any chance?
