Serelda/ Zerelda Cummins that married Robert F. Eagan

Dec 1, 1859, Jackson County, Missouri, Serelda?Zerelda Cummin(g)s married Robert F. Eagan. I cannot determine if she is the daughter of James and Judah Cummins OR daughter of John N. and Eleanor Ellen Barnett Cummings.John and Ellen had a daughter Zerilda according to the 1850 Blue, Jackson Co., MO census, age 10.There is a Zerelda Cummings who married 13 July 1858 Jackson County,MO to Thomas Hutchin. So far I cannot find this Zerelda and Thomas after the marriage.Are there TWO different Zerilda/serilda's, spelling their names Cummins/Cummings?Of course it would be easy IF I could locate an 1850 census for James and Judah Cummins but I cannot.Family "history" has James and Judah having a daughter Zerilda born about 1840 also but I cannot find proof yet.Any help appreciated.
