In the past several researchers have claimed Frederick as a son of Peter Mauck b. 1708 in Germany and d. 1771 in Frederick Co. Virginia. Peter Mauck's descendants are identified in a separate book ("The Descendants of Peter Mauck 1708-1980" by William Wolph). Peter lived in the area of Tom's Brook in what became Shenandoah Co., Virginia. In a deed dated 27 May 1779 (Shenandoah Co. Virginia Deed Book #C, p. 355). Frederick Mauck and his wife Margaret sold land in Tom's Brook to Martin Black, who lived adjacent to Peter Mauck. This land had been transferred to Frederick by the division of Peter Mauck's land. Frederick Mauck who married Motlena died in May 1779 (Frederick Co., Virginia Will Book Deed Book #4, p. 440 and 452) prior to the sale of land by Frederick and Margaret and therefore could not have been Peter's son.
In a Frederick Co., VA deed to a Philip Bush dated 03 Mar 1768 (Virginia Northern Neck Land Grants Book O, p. 128) a George Mauck is listed as owning property adjacent to Bush. Bush's property was on Lick Run, a branch of "Opekon" Creek. Also adjacent to Bush were Jonathan Taylor and Thomas Helm. The property that was purchased by Frederick and Motlena from Jeremiah Wood was originally purchased by Jeremiah Wood 10 Feb 1762 (Virginia Northern Neck Land Grants Book K, p. 358) and lists the adjacent property owners as John Briscoe, Thomas Wyatt and Thomas Helms. In a deed dated 3 May 1760 Jonathan Taylor received land adjacent John Milburn and John Littler. The location of the land of Thomas Helms and John Littler is also shown in an early map ("A Map of the Original Grants and Early Landmarks in Clarke Co., Virginia and Vicinity" by Curtis Chappelear) of grants in this area. Thomas Helms lived on the south side of Lick Run and Littler's Run, John Littler on the north side. Between the two was the area between these two runs. This would appear to be where Frederick and Motlena lived, based on the above deeds.
It is apparent from these and several other VA Northern Neck Land Grants that Frederick Mauck, John Milburn, John Littler, Thomas Helms and Jonathan Taylor all owned property adjacent each other. In the Virginia Northern Neck Land Grants a person who was listed as "adjacent" was the actual property owner adjacent, versus a neighbor's name. This would make Frederick Mauck the above George Mauk, suggesting his full name as Frederick George Mauck, or George Frederick Mauck.
Further confirmation of this appears in a Frederick Co., Virginia deed dated 11 Mar 1779 between Stephen Jones and John Lee (Frederick Co., Virginia Deed Book #18, p. 192). The description of the prior owners of this land prior to John Lee includes George Mauk and indicates Mathias Mauk as George's executor. The deed indicates George Mauk purchased the 125 acres from Jesse and Edward White and Mathias sold it to Michael Slip (no dates given). Frederick
