Birth Between 1804-1805: St. Clair enumerated La Porte County, Indiana2217 as a male age 30 to 40 in the 1840 census. Assume, therefore, that St. Clair's birth occurred between the January 1804 marriage of Francis Peak2334 and Euphey Glore and the birth in 1810 of Ufa Peak, who married iohn Frame1720 in November 1827.

1833 Marriage:1496 Marriage of Sinkler Peek and Lucinda Case on 17 April 1833 recorded in Boone County, Kentucky. The ceremony was performed by J. C. Harrison; the bond was given by Daniel Garrison.

Males 5-10 •• 2
Males 30-40 •• 2 << Sinclair
Female 30-40 •• 1 << wife Lucinda
Household of father Francis Peak2216 enumerated seven households after Sinclair Peak.

Death Prior to 1845: No mention of St. Clair Peake after the 1840 census enumeration has been located. Given the marriage2482 of a Lucinda Peek in La Porte County on 21 March 1845, it is assumed that Lucinda was the widow of St. Clair and that St. Clair Peake died between 1840 and 1845, probably in La Porte County, Indiana.
