My mother's first child was with an un-married man. He appears in my Wiki Tree file as a spouse, when in fact there was no marriage. That causes him to be shown as blood related to my siblings and I. I have looked for help on how to fix this and list him as a partner, or something like that, but either I can't find it or simply don't understand the instructions. He is Peter Everett Johnston (Johnston-9224). I am trying to find his real family and any living descendants while my 90 year old half-brother is still able to meet them. Thanks in advance.
