According to baseball-reference, at least, Thomas Mitchell (Tom) Herr and Howard Bruce (Bruce) Sutter were born in Lancaster, Pennsylvania, USA, but I think the games' databases list them as being from Lancaster, California. I don't know how many other players are identified as being from certain states they're not actually from, when the city names are exactly the same, either. But I know the two above players, at least, are listed in the database as being from the wrong Lancaster in the USA.

You also have Reinder Albertus (Rynie) Wolters listed as being an American, when actually he was from the Netherlands, not the USA. Here is his BB-Ref page:
https://www.baseball-reference.com/p...oltery01.shtml . In his time, his birthplace was Nieuweschans, but in your games' databases, the closest current city/town/whatever that you have listed at present for the Netherlands is probably Reiderland, in the Dutch province/state/whatever of Groningen.
Just some errors you may want to correct in your database later on. There are probably other players that need their hometowns/birth locations updated as well. Thank you for your time and attention. CD out.
