I did a comprehensive websearch and came up dry on a meaning. There are a number of people out there with "Tinaya" as a first name; it's also a Filipino surname and a district on one of the islands in the same country.
Try going to the search engine www.google.com and putting in "Tinaya". There are several of your namesakes out there with e-mail addresses listed. Possibly one of them can help with your question. Good luck!
