I have also been researching my Eardley roots. I have some information that be useful. Your John Eardley may very well be the brother of my great grandmother, Ruth Eardley. The 1920 census indicates that John, who was 30 years old on the day the respondants were to use as the basis for the census data (Jan 1), and would have turned 31 later that year, was living with his mother. His mother's maiden name was Sarah A. Hill. The census indicates her married name as Sarah Eardley (widowed). In addition to John, his two sisters, "Alfie" and Ruth, who is my ggrandmother, were also living there. My grandmother, Vivian, who was 18 months old at the time was also listed. It seems that Ruth's husband, William Fremont Wolff, was no longer in the picture. Family lore has it that Ruth's mother threatened to take the baby from Ruth if she did leave her husband and move back home.
Anyway, here is what I have on the Eardleys:
I'm not too sure yet about the first John and his wife Rachel yet, but all the information I have to this poiot indicates they are the parents of John (who married Sarah). Everything after that is reliable. The number preceeding the names is the generation.
