It was good to come upon your message regarding the McMurdo family.
My 2x gt Grandparents from Scotland are Thomas McMurdo born 1827 Morton Thornhill Dumfries. Spouse Mary Fisher born 1827 Balfron Stirling Scotland. Married on 25 June 1848 Larnak Scotland. They had 12 children of whom their 9th John McMurdo born 16 July 1865 at St Ninians Stirling became my x1 Gt Grandfather.
I have had some problem moving back further in my family at present and wonder if you might have anything that may assist me.
I have yet to follow other leads but after reading your web site I was very grateful.
