I might suggest that the surname is "Donoho". I am not exactly sure when the Donoho family actually came to the Peninsula or how many... but in Kent Co. there was a mention of a Michael Donoho in a will in 1698. In Sussex there was a mention of a (or another) Michael Donohoe in 1717. And in W. Wright Robinson's A History of Seaford, he noted that in 1869 a C. C. Donoho moved to Seaford from Wicomico Co. and founded the Donoho Packing Company that initially packed oysters for shipment on the railroad to the north and later expanded to fruits and vegetables. After searching my Sussex and Kent Co. Will books and the Delaware Public Archives Probate web site, and the Tombstone Books of Sussex Co, I only found Donoho, Donohoe Donaho and Donahoe. So, my guess, that took no more than 5 minutes to check this information and could certainly be wrong, would be that the spelling in the will or transcription was incorrect or just a clerk hearing a name and sounding out a spelling based on what he heard which of course was a common practice and a main reason why there were so many spellings for the same family surname. I once found a relative, Kinzey Collins, listed on a website of transcribed census of 1860 or 1870 as King Collins! That was one I always liked! And my wife's maiden name "McCauley" has been spelled at least a dozen different ways in documents that we have transcribed since the progenitor arrived in the late 1600s including "McAldney" and the winner: "McCobaloy".
