How many wives and girlfriends did Mormon founder Joseph Smith have and how many offs

are his descendants living today proud or ashamed of their gene pool?

I'd be ashamed.... DUM DUM DUM DUM DUM

In April 1841, Smith secretly wed Louisa Beaman as a plural wife, and during the next two and a half years he may have married thirty additional women, ten of whom were already married to other men [243] and about a third of them teenagers, including two fourteen-year-old girls.[244] Meanwhile he publicly and repeatedly denied that he advocated polygamy.[245] Smith told his potential wives that marriage to him would ensure their spiritual exaltation.[246] Although Smith's first wife Emma may have known about some of these marriages, she almost certainly did not know the extent of Smith's polygamous activities.[247] Smith kept the doctrine of plural marriage secret except for potential wives and a few of his closest male associates,[248] including Bennett. Smith's plural relationships were preceded by a "priesthood marriage", which Smith believed legitimized the relationships and made them non-adulterous. Bennett, on the other hand, ignored even perfunctory ceremonies.[249] When embarrassing rumors of "spiritual wifely" got abroad, Smith forced Bennett's resignation as Nauvoo mayor. In retaliation, Bennett wrote "lurid exposes of life in Nauvoo."[250]

That's just one paragraph from the kipped. Make of that what you will.

33 known wives.
Unknown number of girlfriends (though there is evidence that he did have some, while married).
The church (and the women involved) did a good job of covering up "plural marriage" offspring of his, because polygamy wasn't practiced openly then like it was in Brigham Young's administration later...but estimates range from 2-8 offspring other than with Emma (his first wife).

Here's a good reference:

Peace.

33 wives I think 8 children

There are no pr oven descendants.

Brigham Young and John Taylor (the 2ND and 3rd LDS Presidents) both fathered children by polygamy in Nauvoo however.

There were rumors back then of abortions, and condoms were around by then.

His known children (3 sons) stayed in the Midwest with their mother Emma. She and they didn't stay LDS after the church split apart at his death. They were RLDS.

I think one his descendants finally joined the LDS church in the 1950s.
