Regarding the name "Elkanah" (Shmuel haNavi's father in Tanach), I have been unable to find its use as a given name among Jews from any period of history, including today. For example, I cannot find a single rabbi of note that had "Elkanah" as his given name.
Is it correct that there is little to no evidence that Elkanah was ever used as a given name by Jews?
If so, what might the reason be for "Elkanah" not being used as a given name?
