Under search in maps, names come up that aren't in my contacts. How does this happen?

Question

Under search history in the Maps app,...along with all the other places I
did search for, some addresses comes up that I'm not familiar with, and they stay
there. In some cases I didn't search for them at all. Some I may have. A name also
appears, under the address, like "from John Doe". It’s a name that
I'm familiar with my email, but is not in my contacts. Why and how does
this happen?
For example, a person I receive emails from for work, came up as the
"from", and the address, after I searched for it (not on my phone).....I found out
it was the address of his company, I place I've never searched for, nor is
there a hyper-link to it any emails/websites that I could have clicked on
accidentally.
In another example, the beginning of an address “5165” which I may have searched
for and starting typing in came up in the history with several locations that
start with those numbers. Most of them say “from current location”, but one says from
a name, whom again I’m familiar with by email, but is not in my contacts and
have no idea of why the name would be somehow connected to the address.

Answer 1

Thank you for the reply. I really appreciate it. Do you know why the names are attached, as "from"?
I attached a screen shot image. "Harry" and "Angela" are not contacts in my phone. Who would their names get there?
