April 23, 1874 (Anamosa Eureka, 2nd page, 4th column, near bottom)
Frank Langworthy, a lad of some fourteen or fifteen years of age, has been absent from his home in this city for the past two months. His father has come all the way from California to find him, and is anxiously looking for him. Advertisements are being scattered all over the State, with the hopes of meeting the eyes of the wanderer. Exchanges will confer a favor by giving a brief notice of this.–Monticello Express.
[There is one Frank Langworthy on the 1870 census for Monticello, Iowa. Several Langworthys between the ages of 14 and 33 are living with a Jane Langworthy who is 69. It looks like the head of the household is Cyrus Langworthy (27) and his wife Maria (26), although familial relationships are not given, so this is all conjecture. While other family members do show up on censuses before and after 1870, I cannot follow Frank before or after 1870, and I do not know whom his father might have been. Cyrus and another Langworthy family on the same census page appear to be lumber merchants.]
