I'm trying to get proof that Deac. Samuel Chapin and Cicely Chapin had a daughter, Joanna Stebbins
From WikiTree (https://www.wikitree.com/wiki/Penny-74), there is no mention of a daughter named Joanna in Cicely's will. This is supported in the Chapin genealogy by Howard Millar Chapin, Life of Deacon Samuel Chapin of Springfield, page 37, which discusses the marriages of the children of Samuel and Cicely. Archive.org And again on page 42 with an excerpt from Cicely's will. Archive.org
