Thank you for your reply Jean. Yes I know Cathcart is now between Glasgow and Renfrewshire since 1912, I believe, but in 1857 it was in Renfrewshire ony.  Our John McArthur c1828, son of Duncan McArthur and Margaret Smith, was working there then and I am trying to trace his movements and hoped to find him at a farm working in the region of Cathcart.  Hoping he will be mentioned in one of the farm surveys.. He was born elsewhere  I think. We haven't found any McArthur surname in any of three males DNA, or at least three family members autosomal with ancestry.com. But have at least four surnames to go on that do appear in their YDNA with familytreedna'  It was commn for Highland surnames to be named differently  We had another surname the other day and they too have never found  their surname through DNA as yet like us. We only have to deal with 9 as we have done Y111 and it has be narrowed down to the 9 surnames.  So I am hoping to find when the name change took place, or the NPE that was suggested.

regards
