The Bread and Butter of Genealogy and The Secret Button are two blog posts by Ph. D. professional genealogist Sadie McMullon.
Specializing in research for Cambridgeshire, Northamptonshire, Lincolnshire and Bedfordshire, she has a particular interest in placing ancestors in context. That’s illustrated by those blog posts linked from her Genealogy Lantern website.
