An old home like that almost certainly has lead in a lower layer.
If your trim is going to be removed and stripped, you can use the “harsh stuff”! Meaning…the Methylene-chloride based stuff in the garage, where there’s LOTS of air!!!.
If trim is staying inside, I strongly recommend you consider a newer class of strippers: http://www.dumondchemicals.com/smart-strip.htm
They’re more expensive and slower, but you can use them inside, and they’re No-VOC. They DO work though!!
This stuff has been used on many old restoration projects where the “harsh-stuff” just isn’t an option.
A gallon averages about $50.
In a few years, the harsh strippers will be getting rarer.
