Interesting topic.. It would be great to hear a variety of opinions, ideas, and experiences from others.
Of what genealogical value are family stories and written accounts?
Of course it depends on many things including but not limited to who wrote it, why, in what spirit, with how much diligence, their sources, etc. it would be ideal to know all of these before deciding how much credence to lend the particular document or story. To simply accept as fact because it says so and is signed by a respected person is perhaps a bit hasty if all of the facts surrounding it are not known.
Enlightening experience...
From my wife's side of the family i have two handed-down documents written by different people. At face value, they are both well written factual first-hand accounts and memoirs, 17-25 pages typed. They site places, events, dates, and descriptions of people and their exploits.
However...one of them might be "true", but one is most definitely a complete work of fiction.
"Mimi, by Sunny" is written by a daughter for and mostly about her mother Lois who was known as Mimi. The author Sunny was very creative and artsy. As a gift late in life she created this fanciful recount of their life growing up and events that predated her own birth. Loosely based on actual happenings, it could be easy for anyone outside of those in the immediate family to discern fact from fiction within.
She speaks of Mimi's "shock of bright red hair", when in fact she never had red hair a day in her life (supposedly). It was a story. It was meant to bring back real memories of real good times and feelings...and also to make her smile with little inside jokes or teases on mom. Maybe some have eluded us all and were only known to Sonny and Mimi :)
If someone doesn't physically write on the document stating it is known to be fictional, I wonder what future generations will think. Will the unmarked document be held up and trump all rumors of its intent? Will the fiction become "fact"?
Fun stuff...another layer to genealogy and family histories.
Please share any odd cases you've had :)
Cheers!
