HI- I been working on the Costello and costilow family for 15 years or more, but I have stop for the past years. I did see the Teter family in my research and yes, we are part Indian and Irish. They came to Virginia in middle 1700's and Married into the Mattaponi Tribe of King William county, virginia. All my research material is stored in many boxes, but if you could give me Elizabeth parents and grandparents, I could look for them and provide you copies. Costello and Costilow are my relatives too. You can contact me at rutherforda@verizon.net
Cheers, Don
