I don't really have any info on Carol per ser, but I did find the obituary for her father Marion Andrew Cotton (I've attached it for you.) He actually died on 05 Oct 1953 at Roosevelt Hospital in New York City.
I found a Social Security Death Application for his wife Beverly. She died on 23 Apr 2006, and she had apparently re-married named Willard Thorne on 24 Mar 1972, he died 24 Jan 2011. Here is a link to his Find a Grave page: https://www.findagrave.com/memorial/116024614
Willard's obit indicated that Carol married a man named John Locklin.
I know it's been 18 years since your original post, so this is probably old new to you by now, but I wanted to post it anyway, just in case. I hope it's helpful.
