The Northwest Indiana Genealogical Society has added some Lake County databases to their website:
--Index to Will Book "A", Lake County, Indiana--this is an index to the first will book for the county, and it covers the years 1839-1870. There is also a form provided for you to order a copy of the will directly from the county.
--Boyd Home Tourist Records, Merrillville, Lake County, Indiana--this is an index of the guest register for the Boyd Home in Merrillville. The guest register provides a record of the names and hometowns of those travelers who spent a night in Merrillville, Indiana, as they journeyed along the Lincoln Highway in the late 1920's and early 1930's.
These databases are located in the Online Archives section of the society's website and are free to the public.
