This week I had the privilege of speaking to the Ventura County Genealogical Society. As I was finalizing my presentation slides I came across a union catalog of museums, libraries and archives for the central coast of California called the Central Coast Museum Consortium.
You may be thinking "I don't have California ancestors." That's ok, a search on this catalog does show California church histories, cookbooks, and records but there is also at least one resource not documenting California.
Genealogical records, volume II : Port Byron, Illinois records of Methodist Episcopal Church 1833 to 1900, Congregational Church 1849 to 1900, and extracts from the diary of August Henry Wendt 1881 to 1900 / compiled by Genealogical Committee Mary Little Deere Chapter, DAR.
If your ancestor is from Moline, Illinois you may want to see what repository near you has the above title.
A search on the word "church" found 250 results in this catalog ranging from research guides, cookbooks, membership roles, histories, memoirs, encyclopedias, hymns, bibliographies and more.
