Thanks for your response Jillaine! I am finding the same information. Her last name in certain sources is cited as Dearhaugh and in others as Derehaugh, but never, that I can find, as Dearbaugh. I'm trying to figure out how the spelling with 'b' became so prevalent on her profile, but it seems like, regardless, the 'h' is the correct spelling.
Since Anderson has "Dearhaugh", do you recommend changing the lnab?
