Dr George Redmonds, an English academic speciallising in Yorkshire family names and place names, said in a private note to the late Charles Rogers that 'Ogram' started as 'Alfgrym', an Old Danish name which arrived in the SE tip of Yorkshire in the 9th century, during the Danelaw, when much of East England was occupied by the Danes. He quoted examples of how the name had changed over time to 'Ogram'. In the IGI from the 17th century it appears variouslyas 'Augram', 'Oggram', 'Ogeram', 'Ogerham' before settling as 'Ogram'in the 18/19th C.However, there is also 'O'Gram' which appeared twice. John Ogram, a master tailor in Selby, YKS, decided to call himself John O'Gram because he thought it sounded more up-market and would be good for trade.The other example, I'm told, appeared because a vicar had never heard the name before and thought it was Irish and entered it as 'O'Gram' for a baptism. I have alot of Ograms but no Vokes.What is the connection ?
