Timeline (NOTE: the Clifford in these events has not been confirmed to be the correct person,
though no other Clifford FYDELL has been found anywhere):
1870 - "Austin Epheram FYDELL", born 06 Aug 1870, North Gwillimbury, York, Ontario [Familysearch.org "Ontario Births"; IGI says 1871]
1881 - FYDELL family moves from Ontario to Manistique, Schoolcraft Co., Michigan.
1895 - Austin Ephraim FYDELL marries Florence, in Canada(?).

1900 - 07-JAN-1900. Ephraim E. FYDELL, b. AUG 1871, Canada, single (and living with his father, Austin).
How could he have been Clifford’s father in 1896, but single in 1900?
>>> it appears that Ephraim E. FYDELL was the son of a different Austin FYDELL from Clifford’s father.
As of 1900, Austin & Matilda FYDELL (married ca.1871) in Manistique, MI, had 5 and only 5 children, none being Clifford. This Austin was born in England, 1849. Austin & Ephraim E. emigrated from Canada, 1881.
