Marilyn comes from a Puerto Rican family background in New York, born the middle child to Jeronimo and Luisa Ghigliotti and raised in NY, Long Island and New Jersey with her siblings, Evelyn and Leonardo. Of course there's a lot of spunk and attitude. This Jersey New Yorican had to learn to survive many moves and changes in surrounding cultures.

Marilyn got started late when it comes to acting. While going through some life challenges, she decided to study acting at the Actors Training Institute in Red Bank New Jersey with John Eyd, a member of the Actors Studio in New York, where he brought those same acting techniques to New Jersey.
