Individual Details

Although Jacob is listed in many databases as being born ca 1770, I believe it is more likely 1775. He had still not reached age 45 by the 1820 census.

Jacob married 20 Mar 1801 in Jessamine Co KY to Mary Magdalene Rice (she married 2nd to Robert Carey, 1833).

1810 Census, Jessamine Co

Jacob Kellar. 2m under 10, 2m 10-16, 1m 26-45. 2f under 10, 2f 10-16, 1f 26-45 7 slaves


Database online suggests Jacob died 21 Feb 1824. He obviously left several children. One of his sons said to be George W. Rice Keller, b. about 1804, Kentucky; married 28 Aug 1839 at Woodford Co, KY to Mary F. Hampton.

I found the following:
1840 in Clay Co, MO, I found a George W. R. Keller - his household made up of two males age 20-30 [maybe a brother with him] and a female age 15-20.

In 1850, GWR's family did not seem to be in Clay Co, but there was a John R. [Rice?] Keller who was born in Kentucky and some of his children have names very similar to those of GWR's family - they were Elizabeth H, Sarah A., George M., Martha J., James P. & Thomas J.

I believe I was able to locate George and Mary Keller in the 1860 census in Green Township, Platte Co, MO, household 581:
GWR Keller, age 46, b. KY
Mary F., age 37, b. KY
children all born in MO: Sarah F. age 20, Martha A. age 17, Eliza J. age 15, John age 12, Ella Gray age 9, Geo. R. age 4, and Mary age 2.
Also living with them was Asa Smith, age 23, b. KY
and P. A. Hampton, age 44 [maybe Mary's brother?] and a female Hampton, age 21, whose given name looks like Taneri [her name likely misunderstood by the enumerator]

Before 1870, it seems likely that both George W. R. & Mary F. Keller had died. There could be estate records in Platte Co to look for between 1860 and 1870. I found in Weston Township, Platte Co, these two families:
Asa S. Smith, age 34. Sarah F. age 30, MO [would appear to be the eldest dau of G.W.R. & Mary], Geo. K. age 11, and Gustavus W. age 9. And living with them were Mary Keller age 12, and Jefferson Keller age 9. [would certainly seem to be your gg grandfather]
Fielding J. Kirtly, age 29. Eliza, age 24, b. MO [Eliza J. age 15 with GWR & Mary in 1860], Raymond age 2. And living with them were John Keller, age 22, and George Keller age 14.

An online database lists these children for George W. R. & Mary F. Hampton Keller - a list that agrees with the censuses:
1. Sarah F., b. 27 Aug 1840, MO, married Asa L. Smith, 3 Nov 1859, Platte Co, MO Found in Platte Co in 1870, above - Sarah's sister Mary and youngest brother Jefferson were living with them.]
2. Martha A. "Mattie", b. 1843, MO, married 19 Apr 1866, Platte Co, MO, to Thomas R. Smith. Found in Weston Twp, Platte Co in 1870. Thomas Smith, age 23, b. KY, Martha A., age 26. Asa A., age, b. TX and William M., age 1 month.
3. Eliza P. Keller, b. 1845; married 1 Oct 1867, Platte Co MO to Fielding Jeptha Kirtley. Found in 1870 as above with her brothers John and George living with them.
