The DNA Haplogroup for descendants of Archibald Colquhoun, Lauchlin Colquhoun and Alexander Calhoun is R1a1a under the old nomenclature.
One descendant has done SNP testing. This DNA is CTS4179+ and L176.1-.
CTS4179 is a subclade of L448. L448 is a branch of Z284.
L448 can be implied by R1a with the STR YCAII = 19-21, 19-20 or 21-21 and not 19-23.
STR markers can change rapidly. To check for a DNA match SNP testing can be useful.
If you are a direct male descendant of these families, please test your Y-DNA at Family Tree DNA and if R1a1a join the R1a1a and Subclades DNA Project and the Calhoun/ Colquhoun DNA Project.
Please contact me if you have any questions.
