Noted on 2 November 2012:  The contribution of the eminent genealogist, Roger D. Joslyn, C.G., should be recognized before we pass far from Giles Badger.  In 1982, Joslyn published an article, "The English Ancestry of the Newbury Badgers," in "The American Genealogist" (TAG), in Volume 58, No. 1, page 1 (January) and No. 2, page 91 (April).  In the first article, he discussed his commission to do this research, the relevant American sources, and a transcription of the relevant English records he was sent by the County Archivist of the Gloucester County Record Office in England.  In the second article, he provided a genealogy of the ancestry of Giles Badger, as supported by the English records.  These articles are of great importance and can be found either in or through any genealogical or county library in the United States or can be purchased for $10 from TAG online at <americangenealogist.com>.  Under the headings below, I will provide some of the information provided by Mr. Joslyn, indicating by ellipsis (...) genealogical analysis not included.  Before the listing for Thomas Badgeworth (testator of 1544), I am inserting a photo of St. Lawrence Church in Barnwood, Gloucestershire in England.  Before the listing for son of Thomas, first name unknown, I have inserted a photograph of St. Mary de Lode in the City of Gloucester.  Before the listing for John grandson of Thomas, I have inserted a photograph of the interior of St. Mary de Lode, a Norman church perhaps reusing materials from a stone Saxon church.

BADGER GENEALOGY

1.  THOMAS BAGEWORTH the elder, of Barnwood, Co. Gloucester, the testator of 1544, was born say about 1470.  At the time he made his will he had a wife ALYS, at least two grandsons, and possible a daughter.
Children:
2       i.  ______, b. say ca. 1495.
         ii. Margaret?  Perhaps the Margaret Bagworth mentioned in the above Thomas's will.

2.  ----- BAGEWORTH/BADGER (Thomas) was born say about 1495, was presumably of the vicinity of the city of Gloucester, Co. Gloucester, and probably the father of both two two grandsons named in his father's will.  That he was not named in the will may indicate he died before it was made on 6 Oct. 1544.  There is no will or administration for him.
Children:
3        i.  Humphrey, b. ca. 1517-8?
         ii.  Thomas, b. say ca. 1525.  [Joslyn provides much additional information.]

3.  HUMPHREY BADGER (-----, Thomas) was perhaps born about 1517-8 if he was the 34-year-old "Humfrey" of Barnwood who testified in the 1551-1552 matrimonial case of Thomas Badger. ... It is significant that the residence of Humphrey and Giles --Wotton-- was also where John of Painswick's son John lived. ... John Badger of Wotton named four of his sons Thomas, Richard, Daniel and Giles, names occuring in the other Wotton Badger families. ...
Known children:
         i.  Humphrey, of Wotton, parish of St. Mary de Lode, City of Gloucester, Co. Gloucester, where he was bur. 21 Aug. 1628.
         ii.  Giles, of Wotton, husbandman, the testator of 1611.
Perhaps this child:
         iii.  Rose, living 1611; m. ----- Windowe.
Probably these other children:
         iv.  Thomas.
         v.   Richard.  Did he m. in St. Michael, Gloucester, 12 May 1557, Katherine Austen?
                 This couple may have been the parents or grandparents of Giles Badger of Westbury,
                 [whom Joslyn showed was not Giles of Newbury] as the latter had children Austen and                  Richard.
And perhaps:
4        vi.  John, b. say ca. 1540.

4.  JOHN BADGER (Humphrey?, -----, Thomas) of Painswick, Co. Gloucester, husbandman, the testator of 1618 was born say about 1540, no doubt in the vicinity of the city of Gloucester, and he was buried at Painswick, 7 April 1618. ... Assuming that there was just one John Badger in Churchdown at the time, he possibly married there (1) -----; (2) Joan Wever on 24 Jan 1576/7; (3) Margery -----, buried in Churchdown, 30 Dec. 1596; (4) Katherine Etkines in Churchdown, 31 Feb 1596/7 (sic), she being buried there 1 Nov. 1598; and shortly afterwards, (5) Joan ----- (Hodges?), who survived him and was the Painswick testatrix of 1625.
Children, baptized in Churchdown
probably by first wife
         i.   Joan, bapt. 13 Aug. 1564, not named in father's will, 1618.
5       ii.  John, bapt. 20 April 1566.
         iii. Margaret, bapt. 7 March 1567/8; living 22 March 1637/8 when named in will of
                  her brother John Badger; m. by 4 April 1618, John Port.

         iv.  Robert, bapt. 29 Sept. 1599; m. -----, bur. with him in Painswick, 3 July 1621;
