Can Someone Search Archives at Hora

Is there some kind person who would be able to search the archives at Hora for any information on the Margetis/ Marghetti or Marietti family. I am looking for information on date of death of my grandfather George Margetis & any other information on the family prior to 1900.
I think he died approx 1910 on Kythera. I think he was married in 1870s-1880s & had 5 children, 3 boys & 2 girls. I am looking also for information & dates on his marriage to Vasilia Galanis & birth information. I have quite a bit of information on the Galanis line but would love to trace the Margetis line.
