I am wondering if anyone can help me.

My relative William Henry Corrin was b. approx 1882 poss. in IOM. I have been searching for his marriage to Amy Isabella Killey and see an entry in Lawson's Marriage Index but there is no Volume or Page number. Can anyone enlighten me as to why this information may be missing.

I was hoping to get a marriage cert. so I could clarify who William H Corrin's parents are.

Many thanks Barbara
