Turns out Mike's mom was a Grittner--we're related thru the Nabers on mom's side as well as the Sands on dad's side, not to mention family stories featuring Grittners (from the Pierz Journal).
Mike's grandma Elaine was a Block, daughter of Herman and Angie Block. (That's my Josh on the left, and Mike on the right, above). Elaine's in her 90s, and lives in the Villa. Doesn't he look familiar? 😊 This tickles me!
