Looking for knowledge and family

Hello, My name is Tammy (Heidelberg)Hawkins
To my knowledge i am a decendent of Chistian Heidelburg. He would have been my Great Great Grandfather. He was married to a Marthea or Margart that was a former salve that was owned by his family. When i was a child i was always asked were did i get this name not knowing what the meaning of it was until i was older. My little sister attending Heidelberg College for a year and was always asked questions that she could not answer. I would like to know all i can about my historyso that my children will know there full blood line.

Thanks in advanceTammy (Heidelberg) Hawkins
