Series consists of masters of the Family Information Sheets used to compile the list of "Emigrants on Petworth ships, 1832-1837", which comprises Part 2 of Assisting Immigration. These sheets were "intended as a snapshot of families at the time of emigration" and were used to compile an electronic database as well as the published list. The "masters" in this case actually consist of dated and initialled copies of all the sheets created for each name over time, and are chronologically organized within each name so that the progress of accumulation or duplication of information can be followed.
