Essex claimed for the support of Ira Percival, Age 75, Days 365
Ira Percival kept house. The town paid his house rent, and furnished him some wood, but did not actually and entirely support him. Overseers think they advanced him about the State allowance. His daughter and other friends furnish him with the balance of his support. He is a native of New Hampshire; has lived in Essex some thirty of forty years, but there was no evidence of his having acquired a settlement.

use combination of "exact phrase" and "all the words," and be sure to specify pre-1923.
