It’s very obvious that Amil Zola is as old as she says she is, assuming she’s in the same age bracket as her husband who opened the account. Very few younger people would know who Emil Zola was. (One person here does seem to know – hence their question about spelling.) He was the principle defender of Alfred Dreyfus, whose anti-Semitic trial inspired Theodor Herzl to campaign for a Jewish state.
Yes, late life babies existed even back in the day, although they were rarer. We should be treasuring our seniors for what they can tell us of history. (Disclaimer: I’m 72- not old enough yet to be an authority, but working on it. :-))
