Oliver Brewer - How many wives?

Sorting him today.
It appears he had a second wife due to ages of children or perhaps the FAG is wrong and he only had one wife who lived longer than the one attached?

I discovered a Oliver Brewer while looking for husband/children of Matilda Lawson Brewer who is attached to him in some public trees.
I disconnected her at FS but have not created anything for her there.
My focus is getting the family group correct since someone merged and it came to my work flow to resolve data conflicts.
Quite the rabbit hole.
