[1]   The two are once again listed on First Battalion rolls as having paid taxes on 20 Apr 1783.  Now Frederick pays taxes on himself, two horses and seven cattle.  Andrew pays taxes on himself seven horses and 26 cattle.  The tax roll also lists a William Smith Beltz as paying taxes on himself, a slave, one horse and one cattle.[2] The relationship between the three is yet to be determined.

Frederick and William Smith appear on the 1784 Tax Roll.[3] Frederick appears again on the 1787 Tax Roll,[4] the 1788 Tax Roll (with Andrew and William),[5] and the 1789 Tax Roll (with Andrew).  Andrew now pays taxes on himself, Andrew, and four other males.[6] Andrew, William and Frederick appear on the 1790 Tax Roll, now along with a Peter Beltz.[7] The 1791 Tax List includes Frederick, William and Peter.[8] In 1793, Frederick pays taxes on himself and a John Harringer (presumably a farm laborer).  Andrew, Peter, William S and another William (presumably son of William Smith) appear on the same roll.[9]

Frederick Beltz appears in most every tax roll through 1811.  Throughout that time his income does not appear to change much.  In 1811, he paid taxes on himself and one horse.[10]  The fact that he was paying taxes in Loudoun County suggests the Frederick Belse listed in the 1810 census for Bedford County, Pennsylvania is a different person.[11]

Frederick is first identified as a farmer when on 1 Apr 1785 he leases for three life terms 125 acres from George William Fairfax.  The property located in Shelburne Parish on Dutchman Run.  Part of the property adjoins that of the Earl of Tankerville.  Frederick is charged rent of two Pounds 13 Shillings and half Pence per year.  The lease names Frederick’s wife, Catherine and daughter Susan.[12]

On 10 May 1785, Frederick leases from Henry Counce for 142 Pounds part of the property leased by Counce from the Earl of Tankerville in 4 Jun 1762.  The size of the property is not mentioned.[13]

On 9 Aug 1792, Frederick sells the 1 Apr 1785 lease to one Adam Woolf, Jr. for 125 Pounds.[14] On 1 Apr 1796, he acquires from John Potterfield for 260 Pounds 135 acres initially leased by Lord Fairfax to one John Hackle and then transferred to John Potterfield.[15]

The last indenture is dated 6 Apr 1803 and is between Frederick and Jacob Axline.  The indenture indicates Frederick Beltz transferred a lease dated 18 March 1786 initially let by George William Fairfax to a John Hackelroad.  Hackelroad transferred the lease to John Potterfield.  Frederick received 520 Pounds from Jacob Axline.[16] 

The 1830 census indicates Frederick Beltz resided in Waterford, Loudoun County.  He is in his 80s and his spouse is in her sixties.[17]

Frederick Beltz wrote his will on 25 July 1830.  In it he leaves to his wife, Marian, the farm on which they currently reside, all his money and his property.  In it he directs that his three slaves Marian, Lucy and John are to be freed on the death of his wife.  All his remaining property is to be divided between his daughters Susan Ruse, Catharine Naulton, Mary Weiser and Elizabeth Arline.[18]  No mention is made of his sons. 

Based on the above and available church records we can assess that Frederick married first Catharina.  They had a daughter, Elizabeth (born about13 Oct 1784 and died 2 Jan 1789), Susan (born before 01 Apr 1785), Anna Maria (born on 8 Jan 1787,) a second daughter named Elizabeth (born 26 Jan 1789) and a son, Johannes (born about 17 Jan 1791, died 23 Nov 1791).[19] His first wife Catharina dies sometime after 17 Jan 1791, and he marries Marian sometime before 25 July 1830. 

There is no further confirmed information concerning his sons.  However, it is possible that Peter and William Smith mention above are Frederick’s sons but that is beyond the scope of this effort.
