This important work is the culmination of twelve years of detailed investigation aimed at identifying all the people born with the surname Young (prior to 1870) who lived in Strafford County, New Hampshire. It is a truly excellent compilation, very professionally done, and should serve as a model for others who undertake similar projects. The compiler has drawn her information from a thorough study of essentially all the relevant primary sources, as well as from numerous published materials, and arranged it in a basic dictionary format which is very easy to use. The compiler shows that thirty towns that were at some point part of Strafford County had Young residents, and that there were a dozen or more independent progenitors of the Young families in the county who came from England and Scotland in the seventeenth and eighteenth centuries, and from Ireland and Canada in the nineteenth century. The lengthy introduction explains in detail the methodology and the format used. Basically, every person born with the name Young who lived to marry is the subject of a main biographical article which gives all the known information about that person including names of parents, spouses, and children, and all the available vital statistics, information on land ownership, estates, etc. In addition, there are many main entries for men and women who did not marry, but were otherwise important members of their communities, and about whom a good deal of information was found.
