Bear in mind finding the surname Mackay (any spelling) in early NJ--is a real find. The point being find a Robert Mackay in Freehold, Monmouth Co. NJ is a real big deal.
Two men both of Freehold, Monmouth Co. NJ Robert Burnet selling to Wm. Robinson 315a on the north side of Cranbury Creek in Twp of Piscatagua (not sure of spelling). The date of the land deed filed in Middlesex Co. NJ 19th Feb 1705. The two witnesses Peter Burnet & Robert McKay (sic).
I am ASSUMING the said P. Burnet & Robert McKay also were from Freehold, NJ. I need to find the actual location of the property. The witnesses could live near the location of the land being sold.
If this is "our" Robert MacKay Sr. this is the first document I have found dealing with his life in NJ. By this time period he should be of legal age, now we know he was in Monmouth Co. NJ at least by 1705.
The "Bomb Shell" part of this deed is in 1714 (recorded in probate section of the deed), Robert Mackay (sic) was the the only witness alive and he came into court before clerk or JP Thomas Gordon and "being solomonly sworn on the Holy Evangelist of Almighty God" did take an oath he saw Robert Burnett sign said deed.
The point of the part in the probate section--he was still living in NJ in 1714 and he took an oath--QUAKERS--confirm.
So Robert Mackay was not a Quaker as of 1714. And more than likely his first marriage to Ann Brown took place in NJ and not a Quaker marriage. Their children most likely born in NJ. At this point I do not know if important or not, a John Brown of Freedhold, NJ also was a witness and he also took an oath.
Something to ponder.
In the past family researchers have labored under the assumption that families traveled together in groups. Which I think is the correct postion. The next step you need to do is identify which group your ancestors belonged. We have not been able to establish before PA the surname MacKay associated with other Quaker communties.
The question--not addressed by Hunter and others, did Robert leave NJ for PA by himself ? I do not think it would be reasonable that he did.
I think the answer is he belonged to the group of Presbyterian families that removed down from MA to NJ and then later removed as a group to Cecil Co. MD/Nottingham Meeting House area and some then removed down into Frederick Co. VA.
Looking through Hopewell Friends Marriages I see some of the same surnames in that location as appear on the listing of prisoners transported to Boston, MA in 1652: Taylor, Jackson, Thompson, Hogg, MacPherson, Wilson, Moore, Ross, O'Neal, McConnell & MacKay. The question has been asked "How could Robert MacKay a Scotman become a peaceful Quaker ?" Well this question could be asked of all the other Scottish surname listed in Hopewell Friends. There are other Scottish surname: Anderson, Buchanan, Campbell, Craig, Gordon, Hamilton, Hudson, Ingles, Johnston, MacKean, Roy, Sutherford, Moore & Wallace which appear in the early Frederick Co. VA land deeds, all of their surname appear on the Prisoners List from Battle of Worchester.
I hope next week a new batch of film will arrive at the L.D.S. library, I will be looking not only for Mackay but evidence of all the above surnames. I have already noted that a Patrick Inglis of MA purchased land in early Freedhold area. Two Ingles: James & Patrick were prisoners transported in the ship "John and Sarah of London" landed Boston, MA 13 Feb 1652.
There is also a book entitled "NJ Descendants of Mayflower Families". I have not found any MacKay, but I will be in the future looking for some of the above surnames. I did find a John Mackay in MA 1750's that did marry a Mayflower descendant. I need to check those book at Fairfax Public Library for the above surnames. The point being to see movement down from MA into NJ.
I hope to know more about my theory by the end of the month. In any case the key to the parentage of Robert Mackay must be found in NJ. I do not recall any professional historians (published works) or any of our family historian putting forward this theory of the original of Robert Mackay, perhaps this is why since 1927 Hunter B. McKay looked in vain.
