I recently discovered a new tool for people searching for their biological fathers....all you need to know is that your 'donor' was a student (college, medical school etc...) at the time of donation, which many donors were. If you know the exact college/university that's the best - often a clinic/bank is connected to a specific school, but if not check out what schools are nearby. Do a google search for the school in quotations and alumni. Ex: "Augusta State University" and alumni and 1983.
For most medium-large schools they have a classmates.com listing, and it normally comes up as a hit, sometimes on the second or third page. This is a way to bypass needing to be a paid member of classmates.com to access information. Here's the listing for Augusta State University on Classmates.com and the Medical College of Georgia on Classmates.com.
If classmates.com is a hit, there should be a list of every member who listed that school as attended. It should also list the years they attended. For me, I was looking at Augusta State University and the Medical College of Georgia (because I have a hunch he was in science/medicine based on my own interests), and I was looking for men who attended one or both of these schools anywhere from 1979 to 1989.
I wrote down every male who attended either of those schools during the 10 years that I assume they were in college/graduate school (since he was a senior in 1982, but didn't stop donating until 1989 - leads me to assume he was short on money for about 7 years post-college, and most graduate (PhD or medical/residency programs) are 6-7 years in length). I also checked that they graduated from high school around 1978, so that I was not looking at non-traditional students who may have been older and in school at that time.
Then, I went to the Free Birthday Database and entered their name in to see if anyone came up as being born 2/12/61. Since I tested the site to see how accurate it was, and many people I entered weren't in the database, I assumed it was not a perfect system, so I also googled these names, and for many of the men from the Medical College of Georgia who are now doctors, I was able to see photographs of them, and read more extensive biographies.
While many of the men I was able to knock off my list of candidates for finding information that led me to believe that they did not fit the profile, there are still a handful of men who I have no excluded - and of course it is likely that my biological father is not a member of classmates.com and therefore I would not find him this way. BUT, it is another tool for us to use to try and decipher who we are.
