I'm trying to trace my genealogy back to 1870 with minimal cost?

My mom said several years ago that we were related to the Queen of the Roma(gypsies) who are burried in Rose Hill Cemetary in Meridian, MS. I want to be able to either confirm or Deny this rumor. I can trace my line back to my grandparents on either side but past that i am lost. my biggest problem is that i dont have any way to pay for the ammount of public records i would have to send off for, or even for one of the pay genealogy sites. can anyone suggest some way that i can find this info without a major cost?

I beleive that i read someplace that Emil and Kelly were the King and Queen of the Entire Roma Nation.
