Hi,
I would be honored to help in anyway I can. I have some info that might help your husband.. and well lots of people ..Social Security can foward a letter to a person your looking for. You write a letter to S.S Office in your area, asking to kindly foward the letter you enclosed to said person, give as much info that you have,name date of birth last known address .. in your letter to said person, there must be not threats and such, and letter must be in an envelope unsealed so agaents can read it to varify your request. Make sure you leave a way to be contacted. SS will not give you a responce or any info.. but I can tell you they do it they did it for me to find my BF, Good luck and I will see what I can find with the names I have for you. Talk soon!!
