I hope that I have found a connection with your John Chronisters in Texeas. In Grayson and Cooke Counties in particular. My Great Grandfather Frank Allen was born in Sherman Texas (Grayson County in Sept 1852) to Thomas and Rachael (Rachel) Allen. In the 1850 Census Jno Chronister (age 39 born in the Carolina’s) and Jno Chronister (age 13 born in MO) also lived in Grayson County. Yesterday I made a discovery that a Thomas Allen died in Cooke County prior to 1856 possibly with the administrator of his probate as being John CHRANISTER?. Then there is a marriage record between a John Chronister and Rachel Allen in Cooke County on 18 Aug 1856. I am hoping there is a relationship with your MO Chronister’s?
