Looking for my grandpa: radio inventor, patent holder, railroadwireless communication, conductor in New Jersey on Erie Railroad.
He is a huge mystery. Born in Pennsylvania, lived in Baltimore, Maryland before coming north to Newark New Jersey area.
He married twice: first wife died and he later married her nurse and had four daughters - last of whom was my mom.
Can anybody help? No county records found - only Census Reports show him. May have served in WWI - radio & wireless communication research?
Thank you for reading this request - I have been searching for years.
