Have you graduated college? I got my bachelors in 2016.

I am still doing my bachelors actually. The term "bachelor" used to refer to a knight bachelor who was too poor or young to father vassals under his own banner.

Wow. I never knew that.  What other titles did knights have back in the day? 
1_Wizard
A few other I can't think of right now. But by the end of the 13th century, the term was used by junior members of guilds or universities.

What types of guilds were there then?

A type of guild that formed were known as confraternities of tradesmen. Which may be where the for fraternity was derived from.

So basically the Masons were a guild? 
1_Wizard
Yea they could be considered as one. Guilds depended on grants of letters patent by someone of authority to enforce the flow of trade to their self-employed members.
