Firstly, I would be cautious about taking those books like 'Colonial Families of the Southern States' and others like that as gospel.They did not represent research on the part of the author, but often were simply collections of family histories presented to the authors by family members.Also the entries for William and Mary Quarterlies are full of mistakes, and their sources were often the same.For example, one of the William & Mary Quarterlies outlines the descendants of Maurice Langhorne (b. 1721 d. 1791) that had a number of errors.They showed 2 Beverly's, one from each wife of Maurice.One married a Woodson, the other a Miss Muse, and stated that the one who married a miss Muse moved to Phila.The thing is, in this case I already knew the facts exactly as they were because I am descended from Beverly (William Beverly actually).It was a jumble of facts that individually were correct or had some bearing, but combined were wrong.There was in fact only 1 Beverly, who married Susan Woodson, and the other who married a miss Muse, did not exist, however, Beverly's son Alexander did marry a Susan Muse Omohundro AND she and her children moved to Phila AFTER Alexander's death, so the facts are all there, but jumbled up.This is probably because some relative sat down years later and tried from memory to recompile what they remembered, and only got it partially correct.
In fact, with regard to "Colonial Families of the Southern States of America' by Stella Picket Hardy was reviewed in the Va. Magazine as valuable but not entirely reliable.
So, here is what I have on the first 3 generations of Langhornes in America with citation:
John Laugharne of St. Brides married Rebecca Carter (m. dec 1665).
John was in Virginia by 1676 when he appears in the Virginia House of Burgesses court records.He would appear often over the next 10 years, and was a member of the house in the 1680's.
Feb 25th, 1688/9: there is a record of the estate of Rebecca Langhorne widow of John Langhorne mentioning settlement of debts to Miles Cary and another person(who's name escapes me at the moment).
There were 3 children from this marriage:
Children: 1. John Langhorne 2. Maurice Langhorne 3. William Langhorne
Of the 3, only Maurice had issue.The other 2 died young, although both reached adulthood.
Maurice Langhorne, married Ann Cary, daughter of Henry Cary "of the Forest". Henry Cary was the master builder of Williamsburg, William and Mary College and the Governors Mansion in Virginia.
Jan 21, 1694/5 : Maurice signed a document indemnifying William Roscow and Thomas Merry for any loss in the administration of his brother William's estate.
Jan 1698/99:Ann LANGHORN was recognized as his administratrix in a court docket of actions carried over from the previous November, including a report of the viewing of Waters Creek Mill, and new cases and actions for debt. "Ann LANGHORNE adminx of Maurice LANGHORNE decd bringing her action of debt against Robert HUBBARD administrator de bonis non of the estate of Francis RICE deceased during the minority of Mary RICE the only daughter of the said Francis RICE for 5 pounds eighteen shillings and six pence owed by bill under the defts hand bearing the date the 10th of April 1695 to which the deft by his attorney appeared and preyed an (impartance) to the next court, which is grant him accordingly.
Jan 1698/9: Ann LANGHORNE wife of Maurice LANGHORNE dec'd asked the court to appoint Henry CARY as guardian to her son John (here is the John in the 3rd generation).
Children: 1. John Langhorne 2. Unknown Langhorne(there is a tax thitle in 1704 listing the 'Langhorne Orphans', this implies that there was at least 1 more sibling, perhaps more.
Generation 3: John Langhorne (b. abt 1695 d. 1767) married Mary Beverly.This generation I must admit, as I did before I have the least evidence of who this John married.
Children: 1. Maurice Langhorne 2. William Langhorne 3. Mary Langhorne 4. Lockey Langhorne
