Looking for birthfamily!!

:confused: Hi.Looking for birthfamily.I was born in Flagstaff Az,at Flagstaff community hopital on Feb 06, 1971.I was told i have three older sisters,and a storey behind adoption, but of course i dont know how much is correct.My birth certificate has no info regarding anything of birhfam.I only have my name at birth and where i was born.I was told i was sick at birth and a premie.I was adopted at three wks.the only medical info i have is that one of my sisters possibly has epilepsy.It,s kind of scarey reading alot of these posts and seeing that birth certificates are actually altered,it's bad enough that adoptees have very little info.If any of this looks familiar please feel free.I think about all of you often.I do not want to mess up anyones lives just really curious.Thanks to my bmom i had life!!!
