Searching for relatives of Belhamin (original spelling) Krikor (or Kirkor) & Toros (father of Krikor), born Armenia 1847 & 1822 respectively. Toros has occupation listed as Sea Captain. It is believed the family resided in Istanbul, Turkey possibly around 1840's or around Krikor's birth 1847 and had relatives either in Turkey or in Armenia. At some point Krikor may have lived in the UK, entry is unknown. Kirkor married in the UK 1877 and died in the UK. Krikor had sisters in the UK and some information on these relatives has been found.
I would be grateful if anyone has genuine advice on how to search in Turkey and Armenia for birth, deaths, marriages and immigration/residency?
