One of my four gr-grandmothers was Jenny Aldrich born in Mass in 1858.Her father was Horace G Aldrich born in Rhode Island in 1830.Their places and years of birth found per the 1880 & 1900 US Censuses where they lived in Blue Earth County, MN.The pieces found from several online Aldrich family trees and 1850 US Census appear to further make the fit that I have descended from George's gr-grandson Abel (likely more than one so named) whose second marriage was to Mayflower descendent Urania Sprague in 1741 in Rhode Island.
I presume that both your mother and father go back to George Aldrich to give you the 8 ways!One way will suffice for me. But am I being naive to the reality of early times? (grin)Actually, in my case, my father was of second generation German descent while my mother was of English Yankee descent - her mother descended from a NY Pierce and her father was an Atcherson whose forefathers were fromthe woods of Vermont whose progenitor supposedly was a Birtish deserter from the Revolutionary War.
Interesting to hear that there is an National Aldrich Association....serious stuff no doubt.
