About cousins, and information from family! (Oh, and documents)

I went to my cousin Patty's wedding yesterday. (I'm Patti with an I, she's Patty with a Y.) After growing up all my life thinking that we were second cousins, because our moms are "primas hermanas," I found out that it's in fact un-true! I asked my mom, in an attempt to slyly gather genealogical information from her, how exactly they're cousins. I lead off with confirming that it's on my mom's dad's side of the family. Then she tells me that actually her (my mom's) dad and the "prima hermana's" mom are cousins, they're the actual "primos hermanos." Shock and awe!

So in fact, we're third cousins, not second! I still have to figure this out...

Patti ----- Patty (3rd cousins)
Beatriz ----- Teresa (2nd cousins) (She has my mom's maiden name as her second last name, meaning she got the surname from her mom)
Manuel ----- Teresa's mom, ? (1st cousins) (To pass the surname on, she would have had to get it from her father)
Anastacio ----- Anastacio's brother, Teresa's grandfather, ? (siblings)

At this time, I don't have any siblings listed for Anastacio in my database. This is a whole new branch at a high level that I think will be worth exploring. Maybe I can talk mom into willingly giving up information soon. (My parents have strong anti-LDS sentiments, which seems to translate into anti-genealogy as well.) If not, I'll have to hit up my cousin Patty for information.

On another equally exciting note, my documents from Manitoba arrived yesterday while I was away. Some good new leads, a few French terms to translate, and a lot of bad handwriting to decipher! Boy am I glad we mostly type things nowadays! Doctors and others with bad handwriting should not be allowed to write on vital documents!
