Payette Independent Payette, Idaho Jan. 29, 1925 Another Pioneer Passes: Another pioneer has passed the great divide in the person of Jacob Stroup, who was one of the oldest settlers in this section, both as to age and residence, having come to Washoe valley in 1873, and has lived here continuously since that date.  Jacob Stroup was born February 18, 1835, at Tippicanoe [Co.], Indiana, an died January 28, 1925, at his home in Ontario.  The family later moved to Mercer County, Illinois, where he grew to manhood.  From that place they moved to Alva, Missouri, where in 1872 he was married to Susan Draper, and to this union seven children were born, six of whom, with the widow, survive: A.A. Stroup, S.C. Stroup, who reside at Washoe, Mrs. Jessie McCarthy, Frances Russell, and Guy Stroup of Ontario, and Mrs. Alta Coughanour, of Payette. He and Mrs. Stroup celebrated their Golden Wedding Anniversary several years ago.  He, with his family, came to Washoe before Payette was settled and has seen a great many changes take place.  He was engaged in mining in the early days, in Montana, before coming to Idaho, where he has since been a prominent rancher.  He was a charter member of Washoe Lodge No. 289, F. and A. M., Payette, Idaho, under whose auspices the funeral will be held in the Masonic Temple Friday afternoon, with Rev. Reese, of the Congregational Church at Ontario, officiating.  He is a man who will be missed in the community because he has always stood for better things.  His influence has always been on the side of right and justice and he has always maintained the standard of the old pioneers who laid the foundation and ground work for the better things which we are now enjoying in this community.  The sympathy of the community is extended to the bereaved widow and other members of the family. (Burial at Riverside cemetery)

Many have taken Jacob's birthplace to be Tippecanoe, Marshall Co., IN, but based on the location of his parents in the 1830 census, Jacob was born in Tippecanoe County, IN.  This may be an error on the part of the newspaper editor or the informant (obviously not Jacob, who is deceased), but it surely has to be an error.  Jacob's parents did, indeed move to Mercer Co., IL, where they are found in the 1840 and 1850 censuses.  It's Alba, not Alva, which is in Jasper Co., MO, where county marriage records show they married in 1873, not 1872.

Payette Enterprise Payette, Idaho Feb. 5, 1925 PIONEER CITIZEN LAID TO REST Jacob Stroup, pioneer citizen of the Payette Valley, passed away at his home in Ontario, Oregon at 3:30 a.m., January 28th, 1925, after a lingering illness of many months incident to his advanced age.  Had he lived until February 11th, he would have reached his 90th year, having been born on February 11, 1835, at Tippecanue, Indiana.  When quite young he moved with his parents to Mercer county, Illinois, where he grew to manhood.  After making several trips west he settled in Missouri, where on the 2nd of September, 1872, he was married to Susan Draper, who survives him.  Previous to that date he had crossed the plains no less than five times with other hardy and venturesome men of those days who faced the dangers of hardships incident to the transportation of supplies necessary for the civilization then springing up on the western frontier.  In March, 1873, Mr. and Mrs. Stroup left their home in Missouri, expecting to eventually establish a residence somewhere in Washington.  They came as far as Ogden, Utah, by rail (that then being the end of the railroad,) where they purchased an emigrant outfit and continued their journey overland to the Payette valley, where they secured a quarter- section of land from the government by pre-emption and later another quarter section by homestead on Washoe bottom, where they made their home continuously until 1910, moving at that time to Caldwell where they purchased a home.  In 1913 they moved to Ontario, where they also purchased a home.  After living three years in Ontario they came back to the old home in Wash[oe] where they resided until 1920, when they again took up their residence in their Ontario home where Mr. Stroup passed away on the morning of January 28, 1925. To Mr. and Mrs. Stroup eight children were born, one son, Jacob R. Stroup, died in 1906.  The surviving children are: A.A. Stroup, Payette; Mrs. Jessie McCarthy and Frances Jefferies of Ontario, Mrs. Alta Coughanour of Payette, Guy Stroup of Ontario and S.C. Stroup, living on the old home place at Washoe.  The deceased is also survived by one sister, Mrs. Ellen Duncan of Spokane, Wash., 14 grandchildren and two great-grandchildren. During Mr. Stroup's long residence in this community he took a deep interest in all public affairs, serving for many years on the school board of Washoe and contributing in no small degree to the advancement of educational and other interests looking to the development of good citizenship.  Mr. Stroup was made a Mason at Carthage, Mo., more than 60 years ago.  He became a charter member of Washoe Lodge No. 28, A. F. & A. M., at Payette, January 30th, 1892.  He was also a Royal Arch Mason, having become a charter member of Payette Chapter No. 8, by affiliation when the same was instituted November 29, 1892.  To know him well and intimately, as one of his Masonic brothers expressed it, was necessary to have visited him in his home in the days when he patiently awaited the final summons and to have listened to the wonderfully interesting stories he related of the early pioneer days when the courage of men to carry on was stimulated by an optomism that was undaunted by adversity or attending hardships.  Funeral services were conducted Friday afternoon at the Masonic Temple in Payette, where may of the old friends of the deceased were permitted to view the remains, after which the interment was conducted with the last Masonic rites in Riverside cemetery.

It's hard to figure where the 2 Sep 1872 marriage date came from.  Surely the informant is Susan, and surely she knew her marriage date.  Did Jordan Dodd err in extracting the record (see Source No. 1)?
