Would like to hear from anyone that might know this last name.I have not been able to find on thecensus.Could be several variations of spelling.My gr.gr. grandmother was suppose to be a Perkstaff.On her daughters death certificate it said her mothers maiden name was Laura Perkstaff. On her sons death certificate it says her name was Laura Caswell.I need help. At this point I would just like to hear from anyone that carrys the name Perkstaff or knows anyone that does. Under her married name of Gifford she was the executrix of a John Pruxtorph's will in Warren co., NY, in about 1820.Cannot find the will.
