I am not researching these people, just entering information from one of my books, "Allegheny Passage" by Emmert F. Bittinger:
"The Paulus (Bowlus) family was among the early Germanic settlers of Frederick Co., MD.Wilhelm Paulus (age 40) and Jacob (age 18) arrived in America on the Lydia on Sept. 29, 1741."
"They must have come soon thereafter to Frederick County for historian T.J. C. Williams described William Bowlus, a farmer, as one of the 'earliest settlers in the far-famed Middletown Valley, where he owned large tracts o fland.'The will of William Bowlus has not been recovered, but it is said that his children included, Simon, Edward, George, William, Mary, and Elizabeth.There may have been other children."
"The first known record of William Bowells (Bowlus) in Hampshire County is a lease (1761) and release (1762) on 207 acres of land dated Oct. 8, 1762, in which William Bowell received possession from John and Sarah Hite.William Bowell is described as being from Frecerick Co., MD.The Bowells land purchase in Hampshire County took place only two weeks or so following the sale of his land in what was to become Washington County on the Antietam."
"The exact relationships among the Boweell (Bowlus) families of Frederick Co., MD, are not known, but possibly the William Bowell of Hampshire County is the original immigrant or a son of the original immigrant, William Paulus (Bowlus).A son of William and younger brother of Jacob is said by T.J.C. Williams to have migrated westward, finally ending up in Indiana.This description would be consistent with what we know of William, the son of William Bowells."
Some members of this family moved to Westmoreland Co., PA."Most of the Bowell family apparently migrated to places unknown after a few decades."
There is further information on these people in this book.
