Honora's birth is estimated from the only known record of her in the United States -- the 1850 census.
Honora may have been enumerated in the 1840 census as "Anna Walsh". The ages for her son's estimated birth years perfectly fit with the enumeration schedule.
July 29, 1850Census
Honora is enumerated in the 28th District of Jefferson County in the 1850 Federal Census. She was living in her son, Martin's, household. She is listed as being 60 years old, and having been born in Ireland.
Honora does not appear after the 1850 census. She had likely passed away before 1860.
