one of the most frustrating thing ‘s that ever come across is having a few ancestor’s that aren’t traceable, of course this doesn’t mean that they didn’t exist . i often forget that my ancestors couldn’t read or write or speak English. in the beginning of my search for my family history I’ve had been told that some records were not always documented or some records were destroy by either a fire or a flood or perhaps by war, you might want to looked into the delayed births for documentation this means that people gave a oral account of the births and the account was publish look into the family history’s at your local library in their genealogy department.or go to the county achieves in your state. what i like to do is do a crossed referencing check to see if my material or paternal grandfathers had a male ancestor who has been married more then once sometimes it pays off other times its the moment when you say now, wait a minute this can’t be right can’t it?, as to who is your great great great grandmother, as i said copy everything. write it down scan it this will help you in the long run, if you get confused go online to Ancestry or some other genealogy site, if you don’t like to search for your family tree hire a professional genealogist. remember they get paid anywhere from 500.00 to 1000.00 per hour, they looked up anything that you want .
