I found this obituary. You might want to contact these people.
PERERA - ESME ROSE Wife of the late Hector C. Perera (Attorney-at-Law & NP, Nawinna), sister of the late Leslie and Mervyn Perera of Martinus C. Perera & Son, sister-in-law of Aileen, aunt of Nilika and Nalinda, expired. Cortege leaves Barney Raymond Funeral Parlour for cremation at 2 p.m. on 18th Sept. 2008 at General Cemetery, Borella. 397/5, High Level Road, Navinna, Maharagama.
And i noticed that there is a Hector Perera of Madampe in my family tree. Obviously the Hector C. Perera of this obituary is related to Martinus C. Perera. I am wondering if it is the same Hector Perera or different.
