My neice and I were walking around the old Neshaminy Cemetary in Bucks County, PA. There were several headstones for the last name Titus. Not sure of the first names. I was looking at the name because several members of the same family died within a few months of each other. I cannot remember the dates exactly, but they were in the 1860's I believe.
I would be happy to go back and write down the info for you since I do not know where you are located and the cemetary is only a short drive from my home in Feasterville. I am not sure what town the cemetary is located, maybe Churchville.
