Dear Maria, I spent last evening reading some of the DNA/family tree sites on the Internet and it seems that a group should to do it together to get it started. It is not inexpensive. I saw from $150.00 to $!75.00 for the 25 markers they suggest. Being a little suspicious, I don't know if this is more a money making project for the companies or really can be of use to individuals in tracing their heritage. The ROSE Family seems to be ahead of the curve in this and are gaining much information on their family. You could open the following website for an example. I think we need someone with a scientific background to analysis this and give us more insight. I have always thought this might be one route to go after all records have been combed thoroughly. It also looks like the first testing is done through males. The test is very simple and causes no problems. Let's hope someone more knowable in DNA speaks up.
