We have done a lot of work on the Angus HIRD's (or HERD). One HIRD contact in Angus believes there ar three family groups.We each cover a differnet one fromyours ...at least back to 1800.
In ours there were thirty cousins the grand children of Geroge HIRD and Mary LAURENCE.Many of these moved away from Angus.Ther are branches of our family in Nova Scotia, Massachusetts Washington and Oregon as well as many parts of Cotland and England.
Happy to share infofrom Angus where we have extraxts of civil registrations and censuses for many HIRDs who do not fir our lines. Robin ps my emailis shetlandsheep and the isp is btinternetdotcom
