I have some background information on the Darnbrough name. Our family has been traced back to Christopher Darnbrough 1666 in the Ripon area. Also, Michael 1685 of Well Parish. Our family records show Ephriam as a brother to my great,great, grandfather Sampson Darnbrough b1831.There parents were, William Darnbrough married to Ellen Hullah in 1816 in Ripon. They had 8 children including Ephriam and Sampson.I have records for my side of the family however,not complete for the other 7 and their descendants. Do show a Frederick,Jane,James,Peter,Phillip John and Victoria however,not a lot of detail. Not sure if this helps you.
