The only Spann I could find in Pike County 1880 census are
Spann, John L., 33, Cooper,IL. IN. IN.
Rachel, 31, wife, IL. KY. IRE.
Ella M., 11, dau., IL.IL.IL.
Hill, Rosa M.,3, sister-in-law (?), IL.IL.IL.
Spann,Jordan, 62, Cooper, KY.WLS.IRE.
Francis M.,14,son, IL. KY. PA.
Spann,L. (see under Morgan)
Morgan, J.R.,58, Gardner, OH.WLS.MD.
M.E.,48, wife, ME.ME.ME.
Spann,L.E.,19, (no information), IL.KY.KY.
Pleasant Vale Twp.
Willaim 20,son,farm laborer,IN.NY.CND.
Harriet, 10, dau., IN.NY.CND.
Drake,R.G., 41, Methodist Minister, TN.TN.NC.
M.E.,40, wife, IL.VA.MD.
(my note: CND= Canada; IRE=Ireland; WLS=Wales and FRN= France)This could be your Emma as they married young back then. Spann's may not be in county yet. The questionmark after Ada is probably because of birth state of Francis M.'s mother listed as PA. Also one after Rosa Hill age 3 as a sister-in-law is probably because of age.
