I did find one record:

Marcario Rafael Olguin Garcia
Baptized: 11 March 1812 Hidalgo Mex.
fa: Ricardo Antonio Olguin
Mo: Maria Marcelina Garcia

But I have no way to know if this could be him.
I'm real curious if they were in Northern New Mexico and then came south after the Pueblo revolt in the 1600's.

There are alot of Pueblo Indians with the name Olguin/Holguin.

talk to you later!
