My great great grandparents are Sarah Ann Johnston and John Wilson. Her sister Ann Reece was married to Alexander Reece Jr. Both families had a son Stephen. Sarah's Stephen had the middle name Andrew, not sure if Ann's did as well. The Wilson and Reece families became intermingled after their marriages. My grandfather was named John Christopher Johnston Wilson after his father and my understanding Sarah's grandfather.
Both Sarah and Ann continued to live in the Waterborough and Chipman areas of New Brunswick. Sarah died Sept 1, 1889, age 85 and is buried in the Red Bank Cemetery, Queens County, New Brunswick.
I was able to find marriage documents for both Sarah and Ann. I will have to dig them out if you are still interested. Stephen Johnston was witness at one of them. My understanding is that Stephen Johnston and Ann Armstrong are Sarahs and Anns parents. - Jan
