Still searching for parents/siblings of this lady.  Spelling of last name may be anything from Castle to Cassell to Casteel.   She was born about 1825 in Illinois, according to census records.  She married Henry Masoner about 1843, probably in Illinois.  By 1850 they are in Iowa Co., Wisconsin, and from there they went to Henry's home state of TN, and ended up in Texas.   Some researchers think her father may have been the Oliver Castle who was in the 1830 census in Vermillion Co., IL with a daughter under the age of 5, but there is no proof that I know of.   Any clue or suggestion welcome.
