The docs you need to obtain are:
1) The death cert of Wendy Ellen Stigall
2) The marriage record of Wendy Ellen Stigall, (if there is more than one, all of them).
3) The birth/and or bap record of Wendy Ellen Stigall, if Stigall is not her maiden name, then you need to find out what that was.
Any one of theses documents, and the more the better, should confirm her parentage, hence who "JC" was. Marriage and birth/bap records are the primary sources of data, a death cert is secondary. Similar records for her siblings might help you sort out your story.
