You've got quite a range of usable lenses: any 1900 lens and later is perfectly fine.
A Boston shooter might have a locally made Pinkham & Smith. A nice B&L Tessar was a popular choice for shooting in window light studios, and an exceedingly well heeled photographer may have gone for a Portrait Unar, or even a Cooke.
Resist the urge to get a lens obsolete by the time this camera was new. A good Tessar can be focussed and shot with sensitivity... and ease.
