If you have ancestral lines in Scotland, you’ll want to create a collection of Scottish historical and genealogical books to aid in your research. Tracing Scottish lines can be challenging due to clan names and surname adoptions.
One of the books in my online collection is MacFarlane’s Genealogical Collections Vol 1. There are more books to the series that you’ll want to add to your Google or other online library
Once again, thanks to Google Books we have access to it at any time of the day.
