Looking for information on the following Titus Family who lived in Auburn, Shawnee, Co., Kansas in 1880. This information is from the 1880 US Census.

Timothy Titus age 68 born NY Farmer parents born NY
Martha Titus wife age 64 born NY parents born NY
Henry Titus son age 35 born NY parents born NY
Samuel T Titus son age 25 born NY parents born NY

Is this Timothy the same person as Timothy Titus born 1811 (son of Timothy Titus and Margaret Titus) who married Martha Williams? They had a son Henry born 1846 and also had June b. 1839, Egbert b. 1840, Phebe b. 1841, Susan b. 1843, Mary H. b. 1848 and Agnes b. 1850. and lived in Oyster Bay, NY in 1850.
Does anyone have information on the death or burial of Timothy and Martha? Thank you.
