I would love to collaborate, however I myself do not have much on this line yet. I got the names of Opal's parents off of her death certificate. Also I found interesting that their is a son named Miligan listed on the 1880 census born in september of 1879 and that is the only time he is ever mentioned. Could Nelson possibly be a middle name for this son. Just speculation on my part, but I have seen stranger things. Thanks for the nickname, many things are done under a nickname so who knows what I might find.
