Colegrove...female, age 45, born in NY Gordin Colegrove...male, age 15, born in IL James Colegrove...male, age 6, born in IL John A. Colegrove...male, age 4, born in IL I also searched the Cemetery books published by the Lake County Genealogical Society and may have found the burial place of James J. Parker and his first wife, M.

Parker...d. February 4, 1863 at age 37 years, 7 months, 18 days. Hope this helps. Carol
