Looking at the 1881 Census there is a daughter Alice Callister aged 2 - the child may have been Christian Alice Callister - and known by her middle name? You said that Christian A Callisters birth month was April - if the Census was done in March 1881 then that child would have been 2 at the time of the census. Only way I can think to verify this would be to obtain the birth certificate which would have the childs middle name.
