Getting away from the families you have worked on for years can be change of pace that helps you to later take a fresh look at your own research.
I’ve been working my grandson’s ancestry through his 4th great-grandparents. Half of his tree was pretty complete, but his paternal side is new to me. The families are in the same state as my own, rural like mine, and farmers like mine. But the family structure is different and some of the idiosyncrasies are not quite the same. Working on 20th century families is also not something I regularly do so that’s presenting some challenges as well.
I’m making a short list of “revelations” for my own research while I’m working on these other families.
The good thing is that I’m not related to my grandson more than once. The bad thing is that means more families to research.
