I hope someone can help please.

I am looking for the parents of Eliza Catherine Kelly DOB 1863 Douglas, who married John James Skillicorn DOB 1863, 1882 St. Thomas's Church, Douglas. ECK died 1908 and JJS died 1909. I have the marriage certificate which only gives the name of her father as Robert. I would like to know the name of her mother.

Many thanks
