I see here in the Sogn og Fjordane folder that there is a place called Holmedal, which is now Fjaler for Ytre HOlmedal and Gaular for Indre Holmedal.
Maybe Jacob Holme came from Holmedal somehow.
But that (Holmedal) is not Hyen.https://wiki.familysearch.org/en/Gaular_(Indre_Holmedal),_No...https://wiki.familysearch.org/en/Fjaler_(Ytre_Holmedal),_Nor...
and there is no Jacob born in 1857 there.
One must not forget that Jacob that moved to Bergen as a small child either.
