1816 Bridge over branch of Susquehanna River:2729, p. 2724. "An Act to authorise the Governor to incorporate a Company for erecting a bridge over the North East Branch of the river Susquehanna between the Town of Cattawissa and the mouth of Fishing Creek passed the fifteenth day of March one thousand eight hundred and sixteen." Michael Bitler paid one share.

1844 Death:2047 Michael Bitler's death is presumed to be 1844, even though his tombstone reads 1814. A researcher and descendant of Michael Bitler indicates, "I feel that his death date was 1844, and I base that on his tombstone. Of course, there we have a problem. There was a stone cutter in Catawissa who was careless, repeatedly, so unfortunately I do take some of those old stones with a grain of salt, and this being one of them. The stone says 1814. For a long time I was completely confused, until I saw the Orphan's Court/will stuff in the courthouse. The stonecutter simply forgot to add the cross-hatch to the one. Otherwise, Michael didn't do any of the things that are well documented, because he was dead, and it's pretty hard for him to have been dead, when written records show that ‘Michael and his son Samuel’ did this, or owned this, or whatever. However, when the stones were done, there were still children around to order them, but no one lived right in Catawissa, and I think the incorrect date just went by the wind."

1848 Estate Settlement:1904 Michael Bitler was deceased by August 1848 based on "proceedings in the partition in the Orphans Court of Columbia County at August term 1848 upon the Estate of Said Michael Bitler deceased."

1849 Land Sale:1904 On 7 July 1849, Daniel Yetter, trustee appointed by the Orphans Court, Columbia County, Pennsylvania, petitioned the court to sell the "real estate of Michael Bitler deceased of the one part and Samuel B. Diemer of the other part" which is "situated in Cattawissa and Roaring Creek Townships in Said County adjoining lands of J & D Yoder, John Perry, William Rohrbach, Jacob Rohrbach and a tract of land belonging to the Estate of Intestate and Samuel Bitler as tenants in common containing about Three hundred acres on which are erected a furnace dwelling houses and other buildings." Daniel Yetter was the son-in-law of Michael Bitler, married to his daughter Sarah.
