Regina appears in I Am Golda Meir. She nicknames Golda Meir "Goldie" and tells Golda Meir she didn't do her homework.
Regina Medzini (sometimes called Regina Hamburger-Medzini) is likely who she is intended to be, as she was a documented friend of Golda Meir's at that time.
As Regina met Golda Meir in 1906, by the time the Riddles visited in 1909 they would've been friends for approximately three years.
