4.  "Obituary:  Isaac Miller, 1840-1926."  The Democratic Watchman (Bellefonte, Centre Co., PA), 1 Jan 1926, p. 4 (online at the Bellefonte Through the Years web site) [links died]:

Isaac Miller, 1840-1926. The passing of Isaac Miller, veteran contractor and eminently good citizen, marks another broken link in the gradually shortening chain that binds the Bellefonte of today to the Bellefonte of yesterday year.  Mr. Miller died in the Centre county hospital Saturday morning, from heart trouble and dropsy, superinduced by asthma, with which he had suffered more or less for several years.  He had been about us usual up to the Wednesday preceding his demise, but then became alarmingly ill and was taken to the hospital at once. Deceased was a son of John Miller and was born near Hartleton, in Union county, January 4th, 1840, making him age 85 years, 11 months and 13 days.  Having a common school education which was more than most of the boys at that day were vouchsafed he came, at the age of twenty, to Centre county and located on a farm in Benner township.  His father having been a lumberman, naturally he turned to carpentering for which he had a bent and developed exceptional skill.  With a trade learned and confidence enough in himself to feel that he could make a success of it, he married Amelia Straub, a daughter of George Straub, of Benner township and brought his bride to make their home in Bellefonte.  That was in 1865.  Soon thereafter he formed a partnership with the late John Wetzel and they became one of the town's most reliable contracting and building firms.  When Mr. Wetzel retired the late Joseph Fox joined Mr. Miller, and they carried on the business with equal success for a number of years.  As would be supposed, many of Bellefonte's present buildings are monuments to his ability as a conscientious, economical contractor. Among the out-standing of are (sic) the Catholic church, the Lutheran church, the Bush Arcade and Temple court, all imposing structures to which the town points with pride even today. In 1915 he was elected a commissioner of Centre county, along with Wm. H. Noll, Jr., and D.A. Grove, having defeated the present commissioner, Harry Austin, as the candidate of the Republican party.  He then retired from the building business and gave his time exclusively to his public duties.  It is interesting to note that, while in office, Mr. Miller conceived the idea of compelling able prisoners in the county jail to earn their board; and, clothed with the proper authority, he experimented with a gang of them as road builders.   The idea was practical enough, and Mr. Miller personally supervised the gang, but after several days of persuasion he realized the futility of trying to make a convict do anything more than loaf and eat in a comfortable county jail.  He served the county well for four years and then retired. With all his material needs provided for, the last years of his life were spent without concern for the future — for he was a christian man — or regret for the past — for his dealings with all men had been according to the Golden Rule of do unto others as you would have them do unto you. He enjoyed everything in his quiet unobtrusive way.  We have been with him at a Sunday school picnic and on the mid-way of a county fair, and we knew from the twinkle in his eye that he was just as young at heart at seventy as he could have been at twenty.  His one passion was hunting.  Born in the days when game was aplenty and of parents who knew and loved the woods, the lure hung to him to the last, for regularly he took out his license and went for deer every fall and many of them fell at his unerring aim.  We can think of no happier gathering about the camp fire in the happy hunting grounds than that when the spirit of Isaac Miller joins those of George Weaver, James Alexander, Joseph Devling and Simeon Haupt, all companions of the hunt of years ago, and tales of the "Green Woods" are recounted. Mrs. Miller died in September, 1916, and their son William died in infancy, so that only four sons survive.  They are Edw. H., for years a trusted employer of the Phila. Rapid Transit Co., Harry S., Herbert and Morris E., of this place, all worthy sons of an honorable father.  Also surviving him is one brother, Jacob Miller, in Missouri, and a sister in Danville. Mr. Miller was a member of the Lutheran church, the Odd Fellows, the Encampment and Rebekahs.  In fact he was the oldest member of the Bellefonte lodge.  Funeral services were held in the Lutheran church at 11 o'clock Tuesday morning, December 22, and interment made in the family lot in the Union cemetery.

2.  WorldConnect / Ancestry World Trees (online at RootsWeb.com/Ancestry.com).  Has Amelia born in Benner Twp., Centre Co., PA.  While Amelia was definitely born in PA and was living in Benner Twp. with her parents at the time she was married, she does not appear to have been born in Centre Co.  In the 1850 census, her parents were in Spring Twp., Centre Co., PA, but I cannot find her father in the 1840 census — at least, he is not indexed as being in Centre Co., PA.
