I don't know what you could be wrong. If you were using my link, try copying and pasting it into your browser instead of clicking on it. I was just on the site looking for your family (no luck) and everything came up perfectly. You can also try backing out of all your programs and restarting your computer from scratch.

You can write to Social Security and request the information on that particular XXXXX XXXXX. I've just recently found a person for a customer whom they thought died in 1930 who lived at least 20 years after that. The SSDI also gives the county where she died and you can check for records there. There might be an obituary. If it isn't online, check with the GenWeb site for that county in Colorado and see if they have lookup volunteers.
