The 24/7 Family History Circle posted, as it usually does, What's New at Ancestry
On the list was: Missouri Birth Records, 1805-1980 (Updated)
I quickly went and typed in my own surname.
The results turned up 1 person born in 1889, and 3 appearances of another born in 1909.
I knew about the latter, as I discovered her on the Missouri State Archives awhile back. She's a daughter of Sol Newmark and Sarah Nathan (the couple married in the Great Synagogue of London in 1901.) She didn't live long enough to appear on the 1910 census. The 1889 individual wasn't in the State of Missouri database, though I don't know why not. I was aware of Newmarks in St. Louis prior to our family, and they either died or moved before we showed up. I haven't yet figured out whether or not they were related.
However, no other Newmarks appared in the results, and this was supposed to be 1805-1980. That suggested some serious gaps. My great grandfather, Barney, his brother Sol, and other brothers Max and Israel, all reproduced some more, and there were many grandkids. And great grandkids, too.
Since Ancestry allows you to search on just one field, and allows a +-20 year search, I made that the field, and discovered there was a grand total of 4 records between 1940 and 1980. (One of which was a birth certificate from California!)
A little more research revealed there was 1 entry for 1934, another for 1933, and 5 for 1932. I think more than 7 people were born in Missouri from 1932-1934.
In 1931 there's a sudden explosion of results: 50.
In 1930: 509
I'm not quite sure what's going on, as in 1912, the year my grandfather Melvin Newmark was born, there is only one entry. Not him.
I suspect some counties in Missouri may have released some more recent records. The big question in my mind, since there is a significant, if not completely sufficient, privacy window between 1934 and now, is those four *certificates* from 1951, 1966, 1973 and 1980.
I sent Juliana at Ancestry an email notifying her of this issue.
