My father, Joseph Rand Pelky (Pelkey) was born and raised in Derry, NH in 1932 to Joseph P Pelky (Pelkey) (Pelletier) and Beatrice Gile. My grandfather changed his name from Pelletier to Pelkey to Pelky. His father Damase m. to Pamela Ouellet moved the family to Derry abt 1908 and used Pelky on the 1910 Census, and Pelletier on the 1920 and 1930. He died in 1944 and on the headstone in Londonderry he is listed as Pelletier along with his wife Pamela, daughters Sarah M and Antoinette. All my grandfathers' brothers and sisters used Pelletier as the last name. My grandfather changed to Pelkey when he entered the service in WWI and then dropped the e sometime after he was married in 1931. Holy Cross cemetery in Londonderry did not have any headstones with Pelkey or Pelky but according to the Death certificates listing that BJ Shoja has posted thier was a George Pelkey b.1913 d. died 1913 buried there, son of Damase and P Ouellet. He is probably buried with Damase and Pamela Pelletier and not listed since he was an infant. Hope this helps.
