My grandfather Michael Kilker(1870-1935), had a brother, Anthony(abt 1864 -1866) who lived with his parents, Michael(1838=1907) and Bridget(1824- 1913) in girardville, PA. The family name was misspelled in the 1880 census as Killenr. Anthony was last listed in the 1880 census at the age of 14 and was listed as a laborer in the mines. That's the last trace of him I can find, though my aunts used to say he went out west. He was born in PA. And I've lost him.Can anyone help???
