Hi Tammy,
The correct spelling is Sacrey, but the spelling in different records gets changed.
On the Grand Banks website (
http://www.ngb.chebucto.org/) you will find most of the Sacrey's living in Northeast Pacquet (Pacquet), Southwest Pacquet (Woodstock), and Ming's Bight during the 1921, 1935, and 1945 census.
Thomas & Theresa were already deceased before 1921. Mary Ann was living on Bell Island by 1921. I haven't found William in any census records in my research so far. Jane was in Jackson's Arm in 1921.
I hope that helps. If you have any questions about any of Thomas & Theresa's grandchildren specifically, just let me know who and I'll let you know if/where I've found them in the census records.
Melissa
