Muhandiram is a title meaning an appointed commissioner or leader of a locality. The Tamil community have a completely unique and different method of nomenclature. They also, usually, use two names, the furst representing their father's name and the second representing their own. The son of P. Ramanathan would then become Ramanathan Arulanantham, where the son's name is Arulanantham and is prefixed by the name of his father. The Tamils, like the Sinhalese, usually, use an initial to indicate the first name rather than spell it out in its full form.
Women too use the same naming structure but do adopt the husbands name after marriage.
Searching for connectivity using names for Tamils can be difficult unless one recognizes the convention they usually adopt. It must also be noted here that both Sinhalese and Tamil communities maintain a caste system, even until today, and this caste system can also have its influence on providing them prefixed names or titles. Moors, who are Muslims of Arab origin, have multiple methods of naming amongst their community. Many of those in villages and remote towns use their fathers name as a prefix, similar to the Tamils, differing in only by the fact that they may use more than one name for the prefix. The names Muhammad or Ahmed are commonly sued across the board as fiurst names for male Muslims while the names Fathima or Sithy or Ummu or Noor are used for females.
