Ezekiel b 1853 was married to Elizabeth - see 1901 details I posted above
That Ezekiel had a son called William who was 8yrs old in 1901
Wife Elizabeth died - see freebmd
Ezekiel re-married to Sarah in 1907
Ezekiel junior was born 1908
Therefore - William aged 8 in 1901 was his half brother - that's because Ezekiel born 1853 was father to them both
