People can now trace genetic problems back through the generations. Genealogy traditionally takes a lot of time, but with the Internet, younger people are getting involved. It is more convenient for people who don't have lots of time. After the kids are in bed, you can do some base level research on the computer. Some of the Internet's drawbacks are obvious, especially if your name is, say, Smith.
Privacy is also a concern.
Detailed information on living relatives should not be posted. Just as the latest available U.S. census records are from 1920, so most genealogists like to maintain a three-generation freeze on family information, a measure that protects against fraud. For legitimate genealogists, this means looking elsewhere to get the most current data, according to Helm. We recommend that even though the person who has posted the information has verified that it is correct, you should do it also. Most likely, you will pass your information on to others, and one piece of incorrect information on the Internet can really cause problems down the line.
