GARCIA line in El Sagrario, Aguascalientes

Hello fellow members,

I'm so glad to have found this group for our little area in Nueva Galicia
and have enjoyed my genealogy research for some time. However, I've done
my best to trace back my family line on my own but have hit a discouraging
road block. It's time to reach out for help and hopefully other's have
followed this same family line. The references below are all from El
Sagrario, Aguascalientes.

I've researched my father's line (grandfather is GARCIA and grandmother
GONZALEZ). However, the furthest I've reached for certain is Fernando
Fermin Garzia (born El Sagrario, Aguas, 8/25/1754 and Christened 9/15/1754,
married to MARIA ANTONIA ABAD ALONZO VERNALES DE LOS YNOJOS on 3/26/1794).
However DE LOS YNOJOS confuses me because I believe (not sure) that
FERNANDO FERMIN's father was JOSEPH MANUEL GARZIA who married MARIA
ANTONIETA ALONSO DE LOS YNOJOS, on 4/16/1752. Did Fermin marry a
half-sister?

Going further back, (the rest of this line back i'm not confident) JOSEPH
MANUEL GARZIA father was CARLOS GARCIA (baptized 12/1/1705) married JUAN
ARIAS (baptized 5/3/1711) on 2/5/1729. If this information is correct, the
last (stumbling block) information I have is that CARLOS's birth parents
were JOSEPH GARCIA and JOSEPHA FERNANDEZ (Ortis?). I have no information
about dates or where Joseph and Josepha were born/married. This has been
my dead end for MONTHS!

Any assistance or guidance (or education) would GREATLY be appreciated.
I've seen success other's have had here, but have always been reluctant.
But I have nothing to lose, but everything to gain.

Thanks again and sorry for the convoluted story!

Jorge
