Petition for Guardianship for Theressa Froman - Amanuensis Monday

From the Orphan's Court, Mercer County, Pennsylvania, come the documents below. Catherine Saylor Froman's husband, John, was dead. She had seven children who, for reasons I don't yet completely understand, needed the protection of a guardian. She petitioned the court on December 16, 1872, requesting that they appoint a guardian.

Bond - Guardian of Theressa Frauman

Know all Men by These Presents:
That we, S. W. Mannheimer of Mercer County, are held and firmly bound unto the Commonwealth of Pennsylvania, in the sum of one hundred dollars, lawful money of the United States, to which payment well and truly to be made, we bind ourselves, and each of us by himself, for and in the whole, our heirs, executors and administrators, and each of us firmly by these presents. Sealed by our Seals, dated this Sixteenth day of December A. D, 1872
The condition of this obligation is such that if the above bounden S. W. Mannheimer guardian of Theressa Frauman (sic) minor child of John Frauman (sic) late of Mercer County, deceased, shall at least once in every three years, and at any other time when thereunto required by the Orphan’s Court for the County of Mercer, render a just and true account of the management of the property and estate of said minor under his care, and shall also deliver up the said property agreeable to the order and decree of said Court, or the directions of law, and shall, in all respects, faithfully discharge his duties of guardian of said
Theressa Frauman
then the above obligation shall be void, otherwise it shall be and remain in full force and virtue.

Thoughts, Observations, Etc.

This is the first of those four fat envelopes from the Orphans Court, Mercer County, Pennsylvania.
Both Tressa's first and last names are variations of the names in family records. We recognize her as Tressa Froman but this document gives her names as Theressa Froman (on the first page) and Theressa Frauman (on the second page).
Considering that there were 7 children, $100.00 each in bond seems like a lot of money. In fact, The Inflation Calculator tells me that $100.00 in 1872 was equal to $1889.08 in 2012.
Records like these are new to me. Why did the guardian have to give the court money? Taking on the responsibility of seven children seems like enough of a commitment without having to give over $100.00 for each child.
Who was S. W. Mannheimer? I found S. W. Munheimer in the 1870 U.S. Census, living in Greenville Borough (New Hamburg post office), Mercer County, Pennsylvania. He was 29 years old, a D. G. Merchant who owned $3500 in real estate with a personal estate valued at $13,500. Enumerated with him in the same household were Ellie, 20; Nettie, 1; Lizzie Savers, 16; and Raphael Munheimer, 23. He was born in Germany and was a naturalized citizen. I also found Saml W. Mannheimer, in the 1880 U.S. Census. He was 37 years old, a cigar manufacturer, living in Cincinnati, Ohio, again with Ellen and Nettie, plus a son, Charles. Was he a friend of John Froman? They were nearly the same age. Was he was a relative, perhaps an in-law? Did they come from Germany together? And what is a D. G. Merchant?
The only information I gather about John Froman from these pages is that he died before December 16, 1872; that he (probably) owned "about one half of one Hundred Acrs (sic) of land" and that he was probably in debt because those acres were about to be sold.

There's so much more I want to know. I hope the other file is helpful.
