Brother in law and uncle

[Kit]

In the late 1600s/early 1700s were these terms used to mean anything other than:

BIL - husband of your sister/sister in law or brother of your wife

uncle - brother of a parent?

I'm going through wills to work out relationships and need to know I'm covering all potential bases.

Brother-in-law was also used for what we call stepbrother.

And uncle could be used to mean any older male relative. Also of course could be spouse's uncle.

Thanks. I forgot the spouse's uncle when writing this.

Any older male relative might throw a spanner in the works.

Step-brother, or sister, might well be another issue I'm having with this family. The transcripts don't always record widow/er and the wills I've seen so far seem to gloss over previous marriages and assume you know the situation.
