I know the name of the cemetery -- Feriköy Latin Catholic Cemetery, also called Pangaltı Fransız Latin Katolik Mezarlığı in Turkish -- and I know the name of the person I think might be buried there, but I don't know his year of death, the plot number, or even if he's buried there at all. Year of death could be any time after 1860 and no later than 1923. I have checked FindAGrave, nothing came up.
His name is TOMASO LUIGI MADELLA, alternately spelled TOMMASO, and sometimes given with the English version of his name, THOMAS LOUIS MADELLA or TOMAS LOUIS MADELLA.
I'm 90% certain he died in Constantinople. He was Italian, baptised as a baby in Constantinople, in the Catholic Church of SS. Peter & Paul, so he has got to be in the Catholic cemetery. There might be lots of other Madellas in the same cemetery. Tomaso may be in the same grave as other family members. He had 11 siblings, all of whom died in Constantinople between 1834 and 1908. His parents also died in Constantinople and both were Catholics.
His father was Domenico MADELLA, born in Mantua, Italy circa 1783, died 18th Feb 1853, in Constantinople, aged about 70. Ref. Old Parish Death Registers of Constantinople, Church of St. Mary Draperis, Book no. 6. His mother was Anna MARCOPOLI, baptised 7 Aug 1791 Constantinople, died 6 Jan 1861 Constantinople, aged 69. Old Parish Death Registers Catholic Church of St. Anthony of Padua, Book no. 44/491 and Church of St. Mary Draperis.
Short of getting on a plane to Istanbul and wandering around the cemetery, how can I find Tomaso?
