Where did the "Abbott" name come from?

Personally, I have always wondered where our sir name originated from. I know it means “Priest”, like the Abotts(spelled correctly) we see in Buddhist monasteries. I also thought it was only me that had this question, but with Cherrie Ann looking over the website’s "historical timeline," this was the first questions she called to ask me. Although we know nothing of daddy’s father, I surmise there can only be one answer.
Hugo’s mother was named Alberta Clarke, daughter of our great grandparents, Edward and Martha Ward Clarke. On Hugo’s birth certificate, his sir name is listed as Clarke, but growing up with his father in Trinidad and Tobago; we can only assume he took his father’s name of Abbott. Hugo has one living sibling, Mildred, who I found out is living somewhere in Barbados. Tanty Eva and Bunny have some information on her, that when found, she will fill in a lot of gaps in questions we have. I hope to visit or correspond with her soon to find out if she knew Hugo’s father, and where his family is. This venture is opening so many doors into our historical past that I know this site will never be completed in my life time. I can only hope someone carries on the legacy of documentation of our history.
