(4) John Ferguson, born 4 May 1746 in Callicheb, Killmadock, Perthshire, Scotland, died 18 December 1824 in Duanesburgh, Schenectady Co., New York, aged about 90 years; on 1 January 1773 at Kincardine, Perthshire, Scotland filed intent to marry Jennette McEwen, was born 5 February 1752 in Scotland, and died in Duanesburgh on 28 October 1820, aged 68 years.  They are the oldest people in the cemetery on the private cemetery on NYS Rte. 5 in Duanesburgh (owned by F. D. Siegel in 1938) and presumably were the parents of the following:

Children:

1. John, probably he who was born 1783 and died 16 July 1821, aged 38 years.  He married "Eliza."  Although there is an Elizabeth Stuart in the cemetery, born about 1792, died 6 October 1824, wife of a John Ferguson, it may be that this John's wife was actually Elizabeth Boughton, since it was her two brothers, Andrew and Joseph, who witnessed John's will.  "Eliza" does not appear to have buried with her husband, which would stand to reason, since Elizabeth Boughton remarried and moved to Saratoga County.  Further research is needed.  John made his will on 4 July 1821 in Cobleskill, Schoharie Co., New York, and it was probated on 13 February 1824 in Schenectady County.  In it he names brothers James, Alexander, and Duncan, and sister "Jenny Baker" (Jane Becker, below).  The will was also witnessed by Samuel McClallen.
2. Jane (Jean), born about 1775 in Edinburgh, Scotland, died 25 July 1841 (DAR bible 19:17).  Her gravestone in Cobleskill says that she died at age 65 on 26 July 1841.  She married Niclaas Becker, born 27 November 1770, baptized 31(?) November 1770 at Schoharie Reformed Church, died 9 August 1839 (DAR bible 19:17).  His gravestone in Cobleskill Rural Cemetery says "died  9 Aug 183? ae 68yrs. 8mo. 23days."  Niclaas and Jane lived at Duanesburg, Schenectady Co., and moved to Cobleskill, Schoharie County, about 1823.  Their son John Becker married Jane(t) Boughton, Jane Ferguson's young sister-in-law.
