William Dumbreck, born about 1711, and appeared in Aberdeen in 1757. On 25th August 1757, he was described as ‘gardener in Craigtown’. It is considered that this "Craigtown" is now known as Craigton and is close to Dundee, in Fife. William married Mary Anderson of Linlithgow and became the progenitor of the more numerous Linlithgow branch of the family, which was represented in that town until the death of James Dumbreck in 2004 who was the last of the family line living in Linlithgow.  There are still family descendants living in Australia and other parts of Scotland.

William married twice, firstly to Mary Anderson on the 9th November 1736 at Abercorn, Linlithgow and they had 7 children.

We believe Mary Anderson died about 1754, as William married secondly to Marion White on the 9th November 1756 in Linlithgow. They had a further 6 children, however we have no information to date that indicates any survived to continue this family line.
