Don't remember what I've written here about genealogical research. My sister did a lot during a year when she was no longer teaching school. That was back in 1978, long before the internet and the extensive digitization of sources.
A digression: genealogical research appeals to the sort of mind who reads detective stories. Back in the day there was great satisfaction in figuring out connections, assessing what the probabilities were when faced with incomplete evidence, etc. Unless you participated in a group devoted to genealogy, you didn't know whether you were the first to find your great great grandmother, or had some cousins preceded you. All that is, I think, rapidly vanishing. With ancestry.com and family search, once a connection is made it's visible to anyone in the world who wants to look. And with digitized sources, rapidly expanding to all the printed matter which still exists, and searching, no longer do you have to hit the libraries and local historical societies as did my sister; just click the mouse and pay the subscription fees.
Back tot he title. One set of clues to ancestry was generational naming patterns. These days the Social Security administration releases statistics on naming patterns, tracing the popularity of names. (I suspect there's been a recent drop in babies named Karen.) In the old days when family was more important, babies were often named according to a pattern. For example, my great grandfather named his first son Andrew after his father, and his daughter Sarah after his mother. In Scots Irish families the next set of children would likely be named after their mother's parents, and so on. The pattern was strong enough you could use it to deduce genealogy, at least in the 19th century (By the end of the century it was fading; while my father was named after his mother's father, and my uncle had his paternal grandmother's maiden name for his middle name, my uncle's first name and my aunt's name have no identifiable history in the family
We don't have such large families these days, and the pattern of naming has gone. Does that mean that family feeling is less, or just that a custom has faded away?
