Pritchardia on Family Tree Circles

I am searching for my fourth great-grandfather George Pritchard who married Martha. His grandson, the Reverend George Pritchard(who married Eliza Aillen/Aileen/Ayleen-born:22/9/1799--died:4/12/1781) became British Council to Tahiti and missionary as well. I am one of the many descendants of George and Martha Pritchard of England. We are located in the Pacific Islands of American Samoa and Western Samoa. Please I need help on this matter. Thank-you for perusing through this message. Sincerely, Pritchardia
