Hi Debbie, I'm learning more and more as I pluck along on this venture. I was lucky enough to find a church record from Altar of the marriage of my great grandparents Ramon Moreno and Margarita Romero in 1883. They were both 3rd cousins, and had Murrieta linage in each side. Part of the document had a hand written genealogical tree in it. That made it real easy once I was able to have it analyzed. That tree gave me information to go back a number of generations.
During my search I made extra copies of other unknown Murrieta records, along with other family names that I'm researching. Just in case I needed them for future links. I'll take a look and see if Ignacia Murrieta is listed in them. I'll let you know if I find anything.
Also during my name searching on the internet I came across a awesome web site that carried a Murrieta line. And I beleive it is yours. That was a great accomplishment with that kind of information. I plan on putting something up once I get some more information.
