Answer 1

John Boyd died 30 Jun 1864 at Sidney, NSW, Australia. The cemetery name is Church Point, near Lowther NSW. Age 49.

That was all I found at  familysearch.org

Answer 2

John Boyd, born 1815 (Co. Londonderry) to John Boyd and Catherine McCauley, was convicted of Bigamy in Londonderry Assizes in 1836 and transported to NSW for 7 years. If the following entry is not you, then someone else in Australia is following the same search: http://archiver.rootsweb.ancestry.com/th/read/BOYD/2009-09/1252101197 ]
