I'm looking for descendents of William S. Isaacs and Mary E. (Taylor?) Isaacs as listed in District 3, Howard County 1880 Census. ---------Thomas P. O'Donnell and Ada D. (Isaacs) O'Donnell as listed in E.D. 60, Howard County 1920 Census I wrote a letter to every O'Donnell in Ellicott City to no avail. I'm a lookup volunteer for Putnam County Florida if you need help. Thanks John Brown
