The research that had become apparent to several of us was to understand who the Calverts were outside of Chester in the 1700s.
I was not looking to find my family ancestry here but as it turns out, it appears that it is tied from Greene County to the Chester County Calverts who are Irish and Quaker. This caused me to begin looking at what was known about them. A fellow researcher and Cousin, Jim Ray, who descends from Robert Calvert b 1774 the brother of my Ancestor Thomas b 1769 both sons of Isaac has been digging into the PA Calverts for quite some time while my focus was on VA/MD family lines. I exhausted all references to an Isaac who could be the Isaac of Greene County PA but the Isaac Calvert who is documented to be the son of Thomas Calvert b 1710-15 or 1717 and thus have concluded that Isaac of Chester is the correct ancestor and he migrated to Greene County PA.
Jim Ray and Jim Calvert, among others, have been focused upon this for quite some time and also the research into Jim Calvert's ancestor, John Calvert of Mifflin Co b probably 1742/43 at least 1743 or before. A genealogist has been hired a couple of times and the conclusion is that John of Mifflin co lived in Cumberland after 1775 and before being identified in Mifflin.
Circumstantial evidence and secondary records along with family data have both Isaac of Chester and John of Chester being the same two in Greene and MIfflin. A large piece of circumstantial evidence is that the John Calvert of Chester married Jane Swayne who was the widow Mercer of Joseph who died leaving orphans. JOhn married Jane in or before 1763 and is known Guardian of the children in court in 1769 and 1774. Amos and Hannah(who died young) are the children of record. Amos Mercer migrated to Mifflin/Centre County and then across to Belmont County at the same time as John Calvert Jr and his wife Ester "Hettie" Jones. Granted, that is another piece of circumstantial evidence but a solid piece non-the-less.
Descendants of John Calvert of Mifflin and Isaac Calvert of Greene County, are exact matches in DNA for 6 samples. They share a common ancestor. The only one this could be is Thomas Calvert who married Sarah Williamson in 1739. Thus the birth date for Isaac is 1739-1747(ie, if he is the Isaac who married Elizabeth Gart(Cart) Newcastle 1768 and is disowned by the Quakers in 1769, then he is 21 before this time of 1768's marriage). Even if not, Isaac of Chester has his own tax-record in 1769 so Isaac's birth range is determined and it fits the family stories etc. Same with John Calvert who is b 1743 but after 1739 by the same reasoning.
Joseph of Cumberland County is attributed to being a son of THomas Calvert and Sarah Williamson but there is absolutely no reference among those who wrote about Chester, E PA, Quakers, that indicates a Joseph was the son of Thomas. Joseph's father is the Thomas who married Charity Grubb and posted some of the documents that reinforce that Joseph is a son of Thomas but thomas of Cumberland not Thomas of Chester. This Thomas who married charity I also addressed via records of John Calvert who married Jane Swayne Mercer and Thomas who married Charity Miller in court in 1769, who is a Calvert by marriage and also the record that Charity Grubbs married Thomas Calvert son of Daniel.
THis concludes the backwards looking effort to straighten this out because there is so much misinformation and we have other researchers trying to research Joseph and his father. My effort was to provide the reasoning for establishing that Joseph is the son of THomas of Cumberland and not Thomas of CHester and if so, it is of the Daniel Calvert line.
Now more to the point on DNA: We have two descendants who come from what appears to be this family line by way of JOhn Calvert d 1739 Orange Co VA. EFO and Hopewell documentation indicate he descends from the Calverts who are Quaker. BUT the DNA evidence of the two descendants does not match the family line JOhn Calvert and Isaac Calvert which is Haplo Type NOrdic(6 exact matches in two different descents) but the DNA of the two descendants does match those of the Prince William County Calverts- ie, of the descent of George Calvert b 1668 who m among 2 others, Elizabeth Doyne. George is accepted as the son of WIlliam Calvert who is proven and documented as the son of Leonard who was Gov of MD and brother of Cecilius 2nd Lord, son of George First lord.
Thus there is a research dilemma somewhere. DNA points to the Lords Baltimore for these two descendants. One of those two researchers points at the Hopewell Friends line and the other does point to Lords Baltimore but is not as firmly documented. Even so, neither matches the lines of Calverts whom we project as sons of Thomas Calvert who married Sarah Williamson and agreed, it is not proven but it is at least a very good hypothesis which we are trying to prove.
I think you can see the research monkey wrench.
Beyond this is Joseph Calvert who migrated to Elbert Co GA and back north in to Pope and WHite Co IL. Drury Calvert who goes to MS is a descendant of this line. If you can connect with this some how, and keep in mind, I am not expert in regard to Joseph, merely trying to help out, then you can probably gain by going to Calvert discussion group which accompanies the DNA project and deals with the various research/researchers etc.
