1820 Padron (Census) of Jalpa, Zac

Hello,
I've scanned in the images from the 1820 Census of the Parish of Jalpa, Zacatecas. I hope they'll be useful to you, especially since the records for Jalpa in the early 1800s are so scant.

You can download the zip fie from here:

The complete file is about 50MB.

As I understand it, houses or households are separated by a long line. But there are a few symbols that I can't figure out, such as those found in this image:

The names have a cross next to them--does this mean the person has been confirmed?

There's also a symbol that looks like the Greek letter PSY. Sometimes it's next to a name and other times it's given by itself at the end of the household.

There's also a number that sometimes is given at the end of the household, but I can't figure out what this refers to. Sometimes it's next to a name and other times, next to the symbol that looks like the Greek letter PSY.

Any input would be helpful.

Thanks
Arturo G
