I am looking to see if Gunatilake and Goonatilake are the same family. My father's 2 grandmothers are 2 Gunatilake sisters from the Gunatilake Walwwe. (with Kandy connection). In Sri Lanka, often spellings were interchanged in past generations etc. I do have some info about the Goonathilake name as well.If we could communicate.
