Start with one connection.
Bring a person, a place, approximate years, and one question. A township, congregation, school, or employer may reveal records a surname search misses. The custodian can be outside the county.
STOP 01 / PortlandJay County Historical Society genealogy library
Use the local society to identify the right family material.
The society maintains a genealogy library and offers a dedicated Jay County genealogy section alongside its museum collections.
Research details & a question to ask
How to begin
Contact the research address before traveling and describe the family, locality and years. The society asks for advance arrangements for appointment days.
A question you can ask
Which family or local-history material has citations for this person?
Keep in mind
The public overview does not establish that every surname has a file. Confirm exact records and copying terms with volunteers.
STOP 02 / IndianapolisIndiana State Library: Jay local-history publications
A midwife’s or coffin maker’s account can suggest another evidence trail.
The county-history list includes Mariah Mendenhall’s Case Book of Midwifery Calls, 1862–1900, and Coffin Accounts from Edmund Smith’s Ledger, described as an index of names in Penn and Jackson Townships.
Research details & a question to ask
How to begin
Search the listed titles in the State Library catalog and request the exact publication. Ask what underlying manuscript or ledger it represents.
A question you can ask
What event does this entry actually record, and where is the underlying ledger?
Keep in mind
An account is not automatically a birth or death certificate. Check the compiler’s explanation, dates and original source.
STOP 03 / Indianapolis and onlineIndiana State Library county research guide
Take a title and date range to the catalog.
Selected holdings include Tract Book of Entry, 1832–1854; Original Land Purchases; and Wills and Estates, 1838–1847.
Research details & a question to ask
How to begin
Use the county guide to identify a title, then check the library catalog and ask staff about consultation or copies before traveling.
A question you can ask
Can the early land entry link this name to a specific township?
Keep in mind
Published indexes and abstracts are finding aids. Follow their references to the underlying records; the list is not exhaustive.
Leave a trail another researcher can follow.
Save the repository, collection title, dates, volume, page or item identifier, link, and the date you consulted it. Follow an index to the original record when possible. Keep uncertain names and inferred relationships visibly separate from what the source states.
