Weldon, there appear to be two profiles for him.
and also https://www.wikitree.com/wiki/Brown-79095
They have the same year of birth and share a wife but have different death dates. I proposed a merge so that you can compare the two but if they are not the same person please reject the merge.
I put a transcription of the will for the William Brown who died 1787 on one profile. There is another William Brown who died 1785 in Rowan County.
The 1785 will lists the wife as Margaret Brown.
The 1787 Will lists the wife as Mary Brown.
These are two different William Browns. Can you tell from the 1787 will now on the profile if this is the right William Brown? The 1787 will wife is Mary and not Margaret.
I can help you look for some more information once we know which William Brown the profile should represent.
