Some of the names you mention coincide with names in my family but I don't believe that they are the same. There was a Mary Grab, maiden name unknow, she married a Robert Grab. She was born many years before 1964 and she and her husband Robert had 19 chldren. I am sure one of those 19 had to be named Mary but never knew the family to live in California. They had their roots around Harrisburg, Pennsylvania. Robert was the son of George Grab. George was my father's brother (Henry Grab) and the whole family had their roots in Columbia, Pennsylvania. Strangely enough my brother's name was Donald, actually Henry Donald Grab. If you think that any of this is in any way connected with the search that you are conducting please let me know and I will help in any way that I can. Jim Grab
