Lehi was supposed to be of the tribe of Joseph -- a northerner,
and thus heir to Divine promises given to some of the Israelites
who were not of Judah (not ancestors of the Jews).
It has been speculated that Lehi's wife may have been from
another northern tribe -- and that Mulek brought representatives
of some northern tribes with him on his migration to America.
There was an RLDS patriarchal blessing given to an American
Indian during the 19th century, saying that he was of the
"Tribe of Yissachar" -- a northern Israelite group, some of
which must have come with Mulek (as Lehi's wife would not
have passed down the tribal lineage, according to the RLDS).
However -- in Israelite tradition, membership in the tribe can
also be passed down through the mother. Today the children
of a Jewish mother are Jewish.
Or -- perhaps the Book of Mormon is not true.
