Mrs. Shimer mattered and matters. So too did Cinderlla Gregory (who also married and her last name became Lansing. And this despite controversy about the spelling of her first name).
But, I ask: is Mrs. Shimer the only Shimer that matters? My answer? No.
There are other Shimer's that matter -- like Robert Shimer, for example - though only because we share a name, not because we share a history. Henry, though, matters in a different way. He matters because we are Shimer in part because of him,
