I talked to my mother-in-law about your message and yes, this fits into "family legend" very nicely.Remembering that she, like me, is an in-law to Berl's family, it's easy to understand how that she didn't have everything placed correctly.She was thinking that Winnie Stafford followed down Berl's Mother's (also Adams, but no close blood relationship) line.
Her "source" seems to have been one of Berl's now deceased sisters from whom my wife's sister, another of Berl's daughters, also pumped for information but evidently hadn't gotten the "Winnie" connection from.
The Reels Chapel burial reference got me an "Oh YES" response from Mom as well.
The subsequent Half-Sibling Evans relationships are not something that rang any bells, but that too is not surprising.
So, now I have a definite place to begin solid research.Thank you VERY MUCH for the heads-up.
One more thing:You're citing the "IGI."Can you explain what that is, and is this something I might be able to reseach further?
