 LINCOLN, Neb. (AP) — A Lincoln mail carrier faced a difficult task earlier this month when he found a letter sent more than 100 years ago in his pile. 
 
 The letter with a 2-cent stamp showed up in the pile of mail Larry Schultz was sorting for his route in the area June 14, the Lincoln Journal Star (http://bit.ly/2s8Ljld ) reported. Its recipient, Grace Wheeler, died in 1947, and her family home was torn down in 1965 to make way for the Nebraska Capitol's south parking lot. 
 
 The three-page letter from Wheeler's daughter, Margaret Casady, was mailed from Des Moines, Iowa, on June 1, 1914. It's unknown how it appeared in Schultz's stack and has been sent to other family members. 
 
 The letter was slit open at the top, as if by a letter opener. 
 
 Lincoln Post Office Manager Todd Case speculated the envelope had been open for some time because of the discoloration where a letter opener had sliced through it. 
 
 "Probably somebody found this either in an attic, or maybe in some boxes, and didn't know what to do with it and just dropped it in a mailbox somewhere," Case said. 
 
 Former Lincoln Postmaster Doug Emery said that mail can sometimes accidentally get lost within the system or sit in a dead letter office for a while. 
 
 "But I don't see how it sits anyplace for 100 years," he said. "I can't believe it would have been in our possession for 100 years." 
 
 Wheeler was the first woman to be a member of the U.S. Electoral College, and to bring election votes to Washington, D.C., in 1921. Those votes included some cast by women for the first time. 
 
 Wheeler flew the election results, at least part way, in an open-cockpit, two-seater airplane. The votes were cast in favor of Warren G. Harding.

 MUSKEGON, MI – Postmaster William Rowe is searching for the relatives of long-gone recipients after an unopened World War II-era letter turned up in the mail recently. 
 
 The letter was originally addressed to a "Mr. and Mrs. Sensabaugh" at a Washington Avenue home in Muskegon that's now empty, and bore an initial postmark from a 1945 Army Post Office. The return address listed the letter's sender as Sgt. Myron C. Cook, with the letter traveling through the New York city post office at one time. 
 
 There was a more recent postmark on the letter -- from Minneapolis 2013 – printed over the old. 
 
 "We think somebody put it back into the mail stream," Rowe said. 
 
 A vintage sealing material on the back of the letter makes him think the letter has never been opened. 
 
 "We're not going to disturb it until we can see if we can find the family first," said secretary Veronica Mauseth. 
 
 Rowe and Mauseth said the letter was saved from the ordinary "dead mail" pile by a mail carrier who realized that the letter was mailed from an Army base during World War II. The mail carrier – a veteran of the Iraq war – realized that the letter had an interesting story. 
 
 Hoping to find clues into the letter's past, the post office reached out to Richard Mullally, who for years has been documenting the history of Muskegon County's World War II Veterans. 
 
 "I get some pretty unusual requests," Mullally said. 
 
 Mullally said he had a photo and record of a World War II-era Navy veteran named Edward Lee Sensabaugh. He said the last name was a rare one. He planned to do some more research into Cook and Sensabaugh's history.

– When a mail carrier found a discolored envelope among his stash of letters earlier this month, a few things stood out, the AP notes. For one, the envelope had been slit open at the top, apparently by a letter opener, quite some time ago. For another, it had been mailed from Des Moines, Iowa, in 1914 with only a 2-cent stamp. When Larry Schultz tried to deliver it to its intended recipient in Lincoln, Neb., his curiosity about how the letter ended up in the mail 103 years after it was originally sent only deepened, reports the Lincoln Journal Star. Grace Wheeler—who happened to be the first female member of the US Electoral College—died in 1947 and her home was torn down in 1965. In its place is now a parking lot. An official at the Lincoln post office doubts the letter was lost in the mail for more than a century as four names jotted on the back add to the idea that it was previously delivered and read. "Probably somebody found this either in an attic, or maybe in some boxes, and didn't know what to do with it and just dropped it in a mailbox somewhere," he says. "But boy, it would be interesting to know where it was actually located and the story behind that." While its path remains a mystery, the three-page letter sent to Wheeler by her daughter—telling of a "pleasant" excursion and a little boy who liked to pinch—will indeed get delivered. It's headed to some of Wheeler's relatives, now scattered across six states.
