I have a John Thomas Ergenbright born in IL age 24 son of William Albertis and Mary Griffith married on February 20,1882, 1882 in Madison County to a Mary Rosa Dudney born in Iowa age 27 daughter of Abraham and Mary Harris Dudney. Two children were born to them, Ernest and Edna. Mary died in 1901. John later remarried. There are conflicting dates on the date of marriage, in my records. Do you have anything on Mary? I have herobiturary, if you are interested.
