Is "Lubrant" a Polish last name?

Hey everyone! I was wondering if anyone knows if "Lubrant" is a Polish last name? I've been trying to find information about its origin and meaning, but I haven't had much luck so far. If anyone has any insights or resources they could share, I would greatly appreciate it. Thanks in advance for your help!

Anything is possible here. This is a crazy country, really.
However, Lubricant is certainly not a Polish surname.

There are certainly people called that in Poland, most of them around Wloclawek and Kunice.

As the link suggests, it may be a variant spelling of another name.

There are Polish people living in Poland with "Lubrant" last name. So technically it is Polish, but I doubt it originated in Poland. It has a French connotation to me.

There is a word "lubrykant". I don't have to explain the meaning.

Yes, perhaps so.

It may well be a variant of the Swiss name Lybrand or the Dutch name Leibbrandt.

There's also an old and now archaic first name in Northern Italy, Liutprand which Lubrant, Lybrand and Leibbrandt may well derive from.
