Rabbi Hirsh Hurwitz, Rabbi of Sunderland and Leeds - Rabbi H Hurwitz of Sunderland, Leeds - Who were his parents?

On several MyHeritage trees his parents are given as Srol Leib Hurwitz and Musha Fein. There are several siblings also given, one of them a Tamara Selig. Indeed she has a Geni profile - Tamara Selig with those parents.
However, Rabbi H Hurwitz's tombstone clearly gives his father's name as Shmuel. This is corroborated by three of his childrens' birth record indexes on JewishGen all of them give his father's name as Shmuel. (None list his mother's name). Additionally, several of those MH trees have a sibling of Hirsh with the name Sroel Leib. I have no information at all about any of Hirsh's siblings and for all I know he doesn't belong on those MH trees. Can anyone provide clarity?
