I have a photocopy of the original marriage register, obtained from the Maryland Archives.
Children
1. John H. BERRY, b. Between 1827 and 1832, Chincoteague Island, VA; Sandy Hill, MD; Horntown, VA; or South Carolina d. Between Aug 1870 and 1 Jun 1875 (Age 43 years)
This appears to be the area of his childhood home, or at least the home of his parents and/or grandparents.
Notes
As indicated on this family tree, our ancestor John Berry was most likely a son of John Berry Hickman, a Revolution War pensioner, c1763 - 25 June 1843. In his will of 1843, three children of his son John Berry are mentioned (see notes below). According to his pension file, John Berry Hickman (alias John Berry Sr.) resided in Accomack Co., VA.
See notes for John Hickman Berry, father of John Berry, Jr. This family needs further research.
The following notes are from the Miles Files: "John was born circa 1790 at Accomack Co, VA. He was the son of John Berry (Hickman). John died before 14 June 1843. John was named in his father's will on 14 June 1843 at Accomack Co, VA. It was on this date that the will of John Berry Sr. called for the the 3 children of my son John Berry to have $100 each. (NOTE: This probably indicates that his son John was deceased). Source citation: [S688] III Barry W. Miles & Moody K. Miles, Wills and Administrations of Accomack County, Virginia, 1800-1860, p. 60 (will of John Berry Sr.)."
John & Maria had three children who presumably were still living as of June 1843, according to the will of John's father. (source: M.K. & Barry Miles in Miles Files Version 7, Eastern Shore Public Library website)
