My dad was adopted he is passed away now on his death certificate it's shaped his family's name is salvatori the mother that had him Merced County he was zoomed in Stanislaus County adopted by my grandmother Barbara McDonough he also had three brothers that were also adopted from the same mother to the same mother it does State on this certificate that salvatori could have changed the way it was spelled or the name I'm really looking for it because I feel like I've been lost my whole life I'd like to find my family

Can you please punctuate? What is "zoomed". Sorry, can't understand.

With that little info it would be near impossible for anyone on this site to help. You could try to hire a private investigatore, give him the documents you have and hope that he finds a lead. That's really the best option you have.

Call the county clerk where these adoption took place to find out if there are any old record to look through.
