well, then, we are definitely cousins! my great-grandmother Sarah Bricksy Butler McDonnell and my great-grandfather James Butler were Elvina's sister and brother; children of James Butler and Elizabeth Kirby Butler Burton.
Sarah's daughter Grace McDonnell (born here in Boston) and James' son John (aka Jack) Butler (born in NFLD; came to Boston after WWI) married here in Boston and were my grandparents.
How are you related to Wilfred Bennett - who married Gertie Hiscock and lived here in Mass, also? Is he a great-uncle to you?
