Since we match DNA at FTDNA (or you match DNA with some relative of mine whose account I manage) I will now be attempting to see which ancestor(s) we have in common. To start this process I need to know the names of your 4 grandparents and when/where they were born. Even if all you know is approximate dates or countries or states and not cities as much as you know will be a great starting point.
Please consider making a profile at Geni.com and linking your FTDNA results to it. You can read a bit about this here
If you have any other relatives that have tested at FTDNA, please tell me this as well, as it will help me to narrow down the possible ancestors or focus on the most likely areas of the family tree.
Adding a GEDCOM to your FTDNA profile is amazingly helpful, so please consider it.
It is also very helpful if you can upload your DNA data to Gedmatch. You can read more about this here
If you have a public family tree on ancestry.com, please send me a link to you on that tree. I am unable to locate trees on ancestry.com by name of family tree (if anyone out there knows how to do this please tell me!)
If you haven't had any other relatives tested at FTDNA, please consider doing so. It helps a great deal to be able to sort your matches according to which parent or grandparent they are related to.
