I had a really helpful and cheerful person in the Oakland, California, area work with me over the past couple weeks to figure out if the Mary Davis Nickerson in his cemetery was mine or not. There was already a photo of her headstone on findagrave.com. So he very helpfully (cough) took a high-res photo of it, after he (with my help) found it. I guess he thought that's what I wanted, despite what I told him.
I thanked him and told him I appreciated his trouble and his work, but mentioned that I needed some information about that woman, so I'd know it was my relative.
His comment was: What are the odds that there would be another Mary Davis Nickerson in this county? And my thought was: Do you know how common those names are? Mary? Davis? and Nickerson? Really. California had five million people in it in 1927, when (we think) she died.
He really *was* as helpful as he could be, but just matching a name is not good enough.
I come from a family with a common name, too, and it's not good enough. I could tell that boy stories to curl his hair about names repeating down the generations until your eyes cross and you stutter just talking about them all.
Also, no researcher worth her salt would accept "Oh it must be her" as good enough. For pity's sake.
So I'm still on the trail of Mary.
