Can anyone help me unravel the mystery of the Kate Caters of Monmouth.

FOD has a baptism transcription for a Kate Sophia Cater on 27 August 1879 allegedly born to William and Mary Ann Cater of Cliffords Court
but I can find no other record of her birth, death.

Does anybody know what happen to her?

I then have a Kate Cater born 9th June 1886 to Miss Ellen Cater in Monmouth Union Workhouse, who I believe marries a relation of mine Albert Whitburn or does she or was it the one above?
