I don’t think anyone ever said that genealogy was fast. Sometimes things happen quickly but, in my experience anyway, that is not very often.
For example, over a year ago I posted something here about the John Greer and Julia Mary Hopkins family of New York City and made note of the fact that their son David John Greer, his wife Anna, and baby daughter Rita lived in the same apartment building as his mother at 1487 Amsterdam Ave in Manhattan.
I hadn’t learned much more in the next 10 months or so. Then I looked through some marriage indexes for David Greer between 1915 and 1920. I had him living with his parents in the 1915 NY census and then being married in 1920. There was a promising record but it wasn’t the Anna I was expecting.
There was a David Greer marrying a Giovanna Tesio in 1919 and I figured Giovanna could be Anna. So I sent away for the record and when it came it confirmed that this was the correct record. Both parents’ names were listed for David. Age and occupation were also consistent with what I’ve seen before.
Of course solving one mystery always leads to more. As you learn more, you find there is more to learn. That is why genealogy can be so time-consuming and fascinating.
