I'm sorry, but I can only connect three of your marriages, but it may be a small help. The first is the marriage of Ralph Titus and Frances Hill. He was the son of Cornell Titus and Hannah (Utt). I have some data on Ralph's descendants.
7. Ralph Titus. b. Sep. 25, 1823 at Blairstown, Warren Co., NJ. (36 at 1860 census when he and his children were enumerated at Frelinghuysen, Warren Co., NJ, 46 in 1870 at Hackettstown, Warren Co., NJ, 54 in 1880). He was a miller in 1860 and a merchant in 1870. d. May 2, 1899 at Hackettstown, NJ. m. 1st Frances Hill on Nov. 4, 1849 in Sussex Co., NJ. She b. 1830. d. 1859. m. 2nd Lydia Giveans. Elizabeth Titus, age 32, was living with them in 1870. A daughter Nettie, age 24, was living with them in 1880.
The second marriage is John Titus and Anna Freeman. He was the son of Andrew and Martha Mary Cornell.
6. John Titus. b. May 18, 1798 at Hopewell, Mercer Co., NJ. (55 at 1850 census when the family was enumerated at Rush Creek, Logan Co., OH). He was a farmer in 1850. d. Feb. 7, 1857 in Logan Co, OH. m. Anna Freeman, daughter of Henry, on Feb. 13, 1820 at Belvidere, Warren Co., NJ. She b. Aug. 27, 1801 in NJ. (49 at 1850 census). d. Mar. 28, 1867 in Logan Co, OH. Both buried in Equality Cemetery, Rushcreek Twp., Logan Co., OH.
The third marriage was between Keturah Titus and John J. Van Kirk. I have data on their descendants.
6. Keturah Titus. b. 1802 in NJ. (47 at 1850 census). d. Apr. 15, 1883 in NJ. m. John J. Van Kirk, son of James and Mary (Jones), on Mar. 3, 1821 in Sussex Co., NJ. He b. ca, 1803 in NJ. (47 at 1850 census). d. in NJ. He was a farmer in 1850.
I cannot place your Sarah in my data and unfortunately the line goes back before the census is of any use.
Many of the NJ Titus line go back to Content Titus, son of Robert, the immigrant of 1635, as do the three above. The numbers before their names are the generation numbers from Robert Titus, he being #1.
