DNA Testing

I am raising money for DNA testing for my son. My sons father passed away before he was born, so I need this testing so I can get Survivors Benifets for Social Security. Testing is $400 plus $75 for the Medical Examiner to release Jason's blood. I really hesitated on making a Go Fund me page but my family suggested I do so. So here I am asking for a little help. If you can help me out that would be so GREAT. Thank you so much with LOVE and RESPECT.
