14 years of research into the history of Ceylon and colonization. Most people in Sri Lanka were given names like Perera, Corea etc. I wanted to find lost Sinhala last names (because of colonization) and family lineages of historic figures who happen to be my ancestors and their relatives. This is a genealogy book as well as a historic document. If you are a relative of President JR Jayewardene, have an ancestor from the Chilaw Corea lineage, are from a family with a political figure of Sri Lanka, have nobility lineage, want to know about descendants of prominent people in the Portuguese, Dutch, and British periods of Ceylon, this might be the book for you. Some of the families in this book were mentioned in such books as Twentieth Century Impressions of Ceylon, Chieftains of Ceylon, Paul E. Pieris books etc.
