Hi and welcome to the list :) Here are some maps and pictures, lots of facts http://en.wikipedia.org/wiki/Alameda_County,_California and you're pretty close, Niles, Washington Twp, Irvington,Centerville were all pretty close to each other. Interestingly I am familiar with both surnames ou are looking for, I will have to email my sister and see if she remembers where they lived. We lived in Hayward when I was a kid so Im sure thats where t was from. I wouldnt know first names, because back in the 1950's we called people Mr. and Mrs. so I never knew adults first names. I hope this helps you if not let me know and I will see what else I can find, Cris, formerly of the Bay Area, now n Atwater CA.(Central Calif)
