Relocated and Census Tracking notes for Daniel Mertz (H3b3)
Daniel is found in 1870 living with his older brother Benjamin in Montgomery County. He was age 26. A Matilda Mertz was present in that household who I don’t think was a sister nor do I think she was Benjamin’s wife. Could she have been Daniel’s wife.
I cannot find Daniel in 1880.
