I don't have a lot of info but have been given Kidney family info for many years. I show that Edgar and Eliza had at least two children. John Kidney was born 1858 and died in 1916. John married Anna Catherine Gillett. Anna was born in 1865 and died in died in 1924. Don't have their marriage date. John Kidney was my great grandfather.
Edgar and Eliza also had a daughter, Margaret, born 1852, died??? Margaret married Thomas Eliel Fales 30 August, 1868 in Kent County MI. Hope that helps a little.
