There are a lot of people doing a lot of great things to help us in our genetic genealogy efforts. Here are a few resources I think might help.
To start with, you need to make sure you understand your own genealogy. Making a list of your surnames and locations at each generation can help.
More details can be found in my autosomal DNA quick guide.
Knowing your locations can be not only interesting but genealogically valuable.
For those who are a little more advanced, or those who just want to make a pretty picture out of their DNA, try Chromosome Mapping!
