I am searching my family tree, John & Mary Mckillop were my GGrandparents, my Grandfather Archie was their son. He was born in the late 1800's, abt 1880 or thereabout. He married Bessie Bigler my grandmother who was born in Montcalm Co.,Langston Mi. in 1884. Anyone having any information on the Mckillop family of Langston Michigan, please contact me.
