This would give Sidney Rigdon a residence in Pittsburg from some time in March (1819) until some time in May of the same year--something like two months. This would give some support to Mr. Schroeder's statement. But in the biographical sketch of Mr. Rigdon in the "History of Washington County," the date of which was supplied to the writer of it by Carvil Rigdon, Sidney's brother, and his brother-in-law, Peter Boyer, it is said that Sidney Rigdon "studied divinity with a Baptist preacher named Clark in Beaver County, Pa., in the winter of 1818-19 and was licensed to preach." Beaver County is immediately north of Allegheny County, in which Pittsburg is located. Notwithstanding the statement of John W. Rigdon has found its way into the "History of the Church," as above explained, yet Carvil Rigdon and Peter Boyer must be held to be more competent witnesses on this point than John W. Rigdon; and more especially since the inquiry made by Mr. Patterson in his capacity of contributor to the "History of Washington County, Pa.," was made in the interest of the Spaulding theory that requires the location of Rigdon in Pittsburg earlier than 1822, when, it is conceded, he took up his residence there. Had the Reverend Mr. Clark with whom Rigdon studied divinity in the spring of 1819 lived in Pittsburg instead of Beaver County, that fact would scarcely have escaped the searching inquiry made upon the subject. But even if the residence of Rigdon for two months in the year named could be fixed in Pittsburg beyond reasonable doubt the conclusion of Mr. Schroeder as to its effect upon Rigdon's denial of knowledge of the existence of the printing-office of Patterson and Lambdin, would not stand. He puts his argument in syllogistic form, thus: "Rigdon's son says Rigdon lived in Pittsburg in 1818. Church biographers allege that he preached there regularly after January 28, 1822. During 1818 and 1822 Patterson was in the printing business, and Rigdon's statement must be deemed untrue." [116] [Footnote 116: _American Historical Magazine,_ November, 1906, p. 526, _ante_ p. 39.] To which the answer is: By no means; since if it be allowed that Rigdon was in Pittsburg at all, he was there but some two months--and the existence of a certain printing establishment might easily escape his knowledge,--and more especially so since the printing office was under another firm name, that of "Butler and Lambdin."
