Kearns IN Mobile AL

I am looking for information on my husband great-grandfather Joseph Vincent Kearns. He was born in Ireland(as far as we know)aprox 1852, married to Anne Marie Danneburg in abt 1878-79 and died in 1894 in Mobile AL. He was an assistant bookkeeper for James McDonald, Mobile AL.

I am trying to find out the names of his parents & how he died. Appreciate any information someone may have.
