Posting for my uncle...08/23/1963..north detroit general hospital

Hi all...I'm posting for my aunt and uncle...He was adopted.... The cannot obtain any non ID...his birthmom's doctor and his adoptive parents were good friends...what we do know if the following.. His birthdate is august 23rd 1963...He was born at North Detroit General Hospital...His birthmoms name is/was last name is Ruthenburg..or Ruthunburg...First name MIGHT be lynn...He was held in hospital care until november 3rd 1963..not sure why but he was told that's when his (a) parents were allowed to take him home... Just primarily wondering if anyone has been searching for him..or wonders about him..there is speculation that he may have full/half siblings...His adopted last name is zerilli... I've went to the registry at adoption.com and did the multi search nothing came up...So On to the other 30 pages I have left here lol! If it rings a bell feel free to send me an IM..and good luck on all your searches!! Lisa
