To answer the last portion of your question, first, the Teagarden ancestry is very deep, many branches of the family resided in many regions, which makes geneology vast and very intrigueing. The Virginia lineage is explained thoroughly in the Tegarden book... but to give you a breif recap, and to explain which abraham we are looking at, I will extract a few lines from the book, if you have a copy, I am starting at page 34, in the 4th printing of the book.
~Abraham Tegarden (II)
b. 1718 in or near Solingen, Germany
m. August 1743 to Mary Parker at Annapolis, Maryland
d. 1783 in Washington Co., PA. (now Greene Co.) at age 65.
(footnote... this would be our Abraham II, which came across on the ship Harle.)
(p.37)... ~By 1757 we know that Abraham (then of Frederick Co. Maryland), had purchased a large tract of land on the west side of the Monongahela River, deed made at Fort Pitt. In 1759 Colonel Bouquet reported sighting Abraham with his pack train on the trail from Fort Bedford to Pittsburgh.
Abraham Johnson, Gentleman, as his name appears on old records, was one of the first settlers in the beautiful and fertile Patterson Creek Valley, which is about 9 miles west of and parallel to the valley of the South Branchof the Potomac River. Born in 1720, Johnson settled as early as 1742 in Mineral County, West Virginia (then Hampshire County, Virginia) in what is known as the "Northern Neck" lands of Lord Fairfax. Very few tracts outside of Patterson Creek Valley were taken up during the lifetime of Lord Fairfax. To the north the valley was divided into 22 lots and on 6-2-1777 Fairfax granted 46 acres north of Lot 5 to Abraham Johnson, and the survey reads:thence S to...in Abraham Tegarden's line.
... the ruins of the Abraham Johnson home at Reese's Mill mark the place where George Washington and the 1748 survey party were entertained by Johnson.
Within this same time frame, Hampshire County, West Virginia court records reveal the estate records of James Patten, Henry vanMeter executor, with an item for May 10, 1750:...1 qt. liquor, 1 sickle, cash paid TeaGarden 9 shillings; further proof that Abraham and Mary probably settled on the South Branch shortly after their marriage in 1743. If Mary did come from a wealthy family, which we are supposing, they could have settled on what was originally Parker land. This could somewhat explain why Abraham I deeded "Tecart's Delight" to his 2nd son, William in 1753 and Abraham II, the eldest son, was not mentioned.
...Abraham II comes through all of the documentation as a Virginian. Descendants who were furthest removed from Pennsylvania in their residence gave a Virginia as the place of birth, whereas those who remained more closely associated with PA lost the significance of Virginia as the original land fell under the jurisdiction of Penns. 1778-80.
...Our Abraham II and his sons settled in the area of Yohogania Co., VA. and considered themselves Virginians.
I will stop there, as it is quite lengthy, as you can see, and this is the richest part of the book, for history concerns, in the way of land settlement, etc. Abraham II was son of Abraham, who was born in Solingen Germany around 1689, which is the reference in the title of the book... Descendants of Abraham Tegarden.
The examples of land deeds and title abstracts, are printed in the first part of the book, to illustrate the settlements and the patterns taken by the descendants, so we can see where each line of the Tegarden family picks-up and leaves-off, so, there is vast history surrounding the name of Abraham, particularly Abraham II, the one which you asked about!Hope this was helpful, and if you get to read a copy of the book, you will be amazed, it reads like a history book, and is very compelling.
