When I first ran into cases of minor children choosing or being appointed guardians after the death of their fathers, I was unsure exactly what this meant. They had mothers, so certainly little ones wouldn't go live with this other person. Gradually, I realized that these were persons who would look after the child's inheritance. I just ran into a good example of exactly what this means and thought I would share. I hope you find this helpful.
Asa Soule's father died when Asa was 17. This is his request to choose a guardian:
"Know all men by these presents that I Asa Soule a minor above the age of 14 years Son of Josiah Soul late of Duxbury in the County of Plymouth deceased, have named, ordained and by these presents do make and constitute Judah Alden of Duxbury aforesaid Esq. to be my Guardian, with full power and authority for me, in my name and to my use, to act demand, sue for, recover, receive and take into his possession and custody, all and singular such part and portion of estate which is or may be coming to me as heir to the estate of the said deceased, or which by any other way or means whatsoever, doth of right appertain or belong to me. And to manage employ and improve the same for my best advantage and profit during my minority; and to do all and whatever may be necessary in and about the premises, as fully and affectivelly to all intents and purposes as I might or could do personally being of full age; praying that he may be accordingly accepted into the same power and trust.
"In testimony whereof I have hereunto set my hand & Seal this twelveth day of May AD 1807."
