I've just managed to get my tree back to a Mary McMaster (though I imagine there were many).
The one I'm looking for was born circa 1873 in Salt Lake City, UT and was married to Willard Josiah Arnold. They had Margaret Arnold, my great-grandmother (and most likely more children as well).
I'm working on documenting 8 generations back on my umbilical line (mother to daughter) to particpiate in the mtDNA project.( http://feefhs.org/misc/frg-chg.htmlhttp://feefhs.org/misc/frg-chg.html ) Mary makes generation number 6 for me...
Any help or information on Mary and/or her ancestors would be greatly appreciated!:-)
