This may not quite qualify, as neither of these people were particularly only well-known at the time of my grandchildren's birth, but my grandson
Abraham (nn
Bram) was kind of sort of named after
Abraham Lincoln and my granddaughter
Lucille (nn
Lucy) was kind of sort of named after
Lucille Ball. "Kind of sort of" means that the name was loved in any case, but the fact that
Lincoln and Ball bore the names was an additional factor in their favor.
