Newf on Family Tree Circles

I was born in Rovigno when it still belonged to Italy to Francesco and Lucia Ghersa in 1942.That area is now a part of Croacia.I came to Canada in the early 1960's.I know I had an uncle who went to the U.S.A.I often wondered why my name was changed to Stambolic when I was a young boy about 13 yrs. old.I know on my mother's side there were Stamboli's but my name was always Ghersa like my father's until then.If anyone thinks they might know someone of that family or can shed some light on why my name might have been changed it would be interesting to know.Thanks

My mother's father-James Thomas Abbott of James and ? -married Rhoda Fisher of Joseph and 'Suzie'Fisher in 1901 at Bonavista,Newfoundland(now Canada).Rhoda died at about 47 yrs.old.Abbotts seemed to settle that area in 1700's.William,Thomas,Hugh,and Stephen Abbott all married there in late 1700's.If you have any info on Abbotts going to NFLD.,Canada at that time I'd like to know from where in UK.Also if anyone knows who was mother to James Thomas Abbott and married to James Abbott.They married no later than 1873 as James T. was born around then.There were a lot of James Abbotts at the time so it's confusing.-Tks. Below is a picture of my grandfather,James Thomas Abbott-maybe in late 1940's when he lived in Hodderville,NFLD.He married someone(?)from there if anyone remembers-Thanks.

My first known ancester is William Stead who married in 1788 at Bonavista,Newfoundland (now part of Canada).Thomas Stead (my great great grandfather lived in Bird Island Cove(now Elliston),Newfoundland.He had 11 children-Elizabeth(1821-),Benjamin Mar.Elizabeth Romaine;Ann Mar.James Porter;John;William Mar.in 1853 Marie Hobbs(my father's grandparents);Thomas;Samuel;Job;Andrew;Frederick(1840-)and Theophilus.I think the last 4 brothers moved to Little Catalina,Newfoundland,Canada in the mid 1800's as their birthdays match up in the census reports there.I'd love to talk over info with interested Steads in that area.
The Steads went to NFLD.,Canada in the mid 1700's-some say from Ireland-others Northern England. They were fishermen but brought with them musical,building,and craftsman skills.My father built boats and crafted violins on which he loved to play Irish jigs.They also have a poetic nature-writing of songs and poetry.
I would love to have ideas on where they might have originated from. If anyone is interested I would appreciate any ideas or info.-Irene Stead
