Don't know you need to look, I’ve never looked at a Syracuse, NY directory however they normally list people and businesses. Look at “Plank”.

If this were my project I would look at the Cleveland directories find out when Prechtel arrived as a gunsmith then go to the old newspaper files and see if there is a story about his new business with his background history. Next would be to find his obituary, that should also list a Lefever connection if there was one. Joseph Singer’s does.
