This past Christmas Eve, my mom took me on a tour of the houses where her family lived just across the Ohio River in Bellevue, Ky.
It included my great-grandma Mamie’s home—an old photo made it into a book on Bellevue by
Arcadia publishing.
Google Book Search does it again:

The house my mom’s dad built on the same street has burned down, but Mom showed me where she babysat and where her best friend lived. A grocery store down the street is now a house. Mom said she’d stop after school, pick out what Grandma needed for dinner, and add it to the family's tab (try that at Super Target).
My Great-grandma and Great–grandpa Frost’s first home looks a lot smaller now than in this photo from around 1925 (
Family Tree Magazine readers might remember the picture from our
September 2008 house history research guide.)

I remember the house below (Google Maps does it again), situated right by the railroad tracks, where the same great-grandparents lived in their later years.

At Christmas, the whole family—their five kids, at least a dozen
grandkids and several of us great-grandkids—would all squeeze inside.
Some of those great-aunts and -uncles and second cousins I haven't seen
since Christmases at Great-grandma's.
It's neat to be able to visit your ancestral homes in person, but you may not have to drive around to see them.
