FREE UNTIL 10/14/2000 on Ancestry.com The only thing I noticed in this database is that they transcribe "H" to mean husband and looks like to me it should be Head of Household. Good Luck! Jeanne Polries PENNSYLVANIA 1910 CENSUS MIRACODE INDEX To search this database, go to: http://www.ancestry.com/search/rectype/inddbs/5103.htm This database is an index to the 1910 U.S. Federal Census for the state of Pennsylvania. It is searchable by head of household. The 1910 Miracode indexes records with the following information for each person: name, relationship to head of household, color or race, age at last birthday, marital status, visitation number or family number, place of birth, county, township, and enumeration district number. The information found here will lead researchers to the location of their families in the actual 1910 U.S. Federal Census schedules. The corresponding census images for this database will be posted within the next few months, and the Miracode indexes for other states will follow in upcoming weeks. Miracode is a slightly modified version of the Soundex indexing format. Miracode and Soundex are indexes based on the pronunciation of a name, rather than the name's spelling. Surnames are coded and then arranged numerically by their codes. Miracode was employed in 1910 only for the following states: Alabama, Arkansas, California, Florida, Georgia, Illinois, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and West Virginia. For more information, see Michael John Neill’s two-part series of articles entitled "Soundex" in the Ancestry Library at: http://www.ancestry.com/library/view/news/articles/2253.asp The omission rate in the 1910 Miracode/Soundex appears to be greater than in most other indexes. Not everyone enumerated on the 1910 census schedules is on the Miracode indexes, as some names were missed or misread by the indexer. It is especially advisable for researchers to continue a search in the actual schedules even though a name fails to appear in an index.
