Apologies for not seeing this post sooner. I actually haven't researched the Piers/Peers line for a couple of years because I no longer have time to pursue Genealogy Research. So, I'll be drawing on my memory here.
Unfortunately, no I do not have any information on Alexander's parents.
Please understand the LDS information simply led me to research down another path. Prior to seeing the information in their database, I did not know our branch of the family spelled the name as "Peers" for 3 generations.
In regards to the variant spellings. I fully appreciate that we have cousins who spell the family name Peers. For some reason my husband's Great-grandfather adopted the Piers spelling although his father used the Peers spelling.
It is very clear in "The Valley of Remsheg" that the Piers of Pugwash and the Peers of Wallace Bay are all in the same family and descendants from Alexander. The author even makes note of saying he didn't know why the Piers who moved to Pugwash adopted a different spelling. (My husband's grandfather & great-grandfather after him immigrated to USA from Pugwash, Nova Scotia. Additionally, he has cousins who still reside there today.)
There are documents dating to just prior to the American Revolution that reflect several spellings of Alexander's surname. Spellings that I have seen for this surname have been quite variant. Peers/Piers/Pierse/Pears/Pearce/Pierce It's made the need for documentation that much more important.
Since that's clarified, let me explain: The LDS was not my documented source/s. Like you, I do not consider information from the family trees to be trustworthy. Too many times I've see discrepencies in undocumented trees. The documented sources I have used are as follows:
1. Books in the Mayflower Society Library located in Plymouth, MA. This library has an entire section of books on American Revolutionary Loyalists; who settled in Canada after the American Revolution.
2. "The Valley of the Remsheg or History of Wallace Bay Nova Scotia". by H.R. Brown published under the auspices of the North Cumberland Historical Society. It is the results of 40 years of research. This particular book list descendents of the Peers/Piers families from the time of the American Revolution to the late 1950's.
3. Ships Records
4. Census Records
5. Town Records (marriages, births)
6. National Archives of Canada
7. American Revolution Muster Rolls
8. American Revolution papers (petitions/public papers of military leaders etc...)
9. New York Maps/Land Records
I have not been able to conclusively trace this family prior to the American Revolution. Unfortunately, I don't have the time to do any more research.
If I had time, below are the two leads I would follow up on. (neither is proven fact)
1st Lead: Seven (7) Piers/Peers/Pears/Pierce brothers who lived in NY prior to the American Revolution descended from immigrant Henry Piers (that was the spelling) of Yorkshire, England. Some lived on Courtland's Manor in Dutchess County NY. Two (2) of the brothers withdrew from fighting in the American Revolution because of hardship on their families & they remained in NY after the American Revolution . Five of the brothers were sent to Nova Scotia. Three (3) settled in Nova Scotia. Two (2) settled in New Brunswick.
2nd Lead: The boys were in NY prior to the American Revolution were descendants of the Pierce of Plymouth County, MA. I have been to the Middleboro, MA library (where several Pierce families still live today) and researched through their very old and fragile record books. Although their is a reference to one of the sons going to NY, I could not conclusively determine that the Piers of NY descend from the Pierces in in Plymouth County.
Note: The two Piers families who remained in NY after the American Revolution spelled their name Piers. However, when Samuel and Caleb's military leave was referenced in the "Public Papers of George Clinton", Govenor of New York, 1778, their names were spelled Pears in the document. So, I'm left to conclude the spelling was dependent upon the interpretation of the person writing the document.
