Simran tends to be a Punjabi and/or Sikh name.I was wondering about that too. I've never met ANY Indians with the same first and last name... Or any non-Indians, for that matter (except maybe one whose married name was the same as her first, but that doesn't count). Her name does sound oddly similar to Sirhan Sirhan (who isn't Indian).
Most female Sikhs take the surname Kaur, and most male Sikhs take the surname Singh.
Not all of course, but Kaur is definitely a good bet on a potential surname for her, especially so for an unmarried female.
MOO.
