Births Mar 1911
Heath Florence Chorlton 8c 886
Births Dec 1914
HEATH Arthur P Davison Chorlton 8c 1636
The middle initial is wrong, probably a typing error on the original, well it seems that Emily born in 1870, was approx. 17 years older, that would explain him adding 10 years to his age! There are quite a few Arthur's showing up in 1911 as 'overseas military' so I think you're right in saying he may be at sea.
The 1891 census has his father as William, I'm wondering if Charles Frederick was possibly an uncle, I'll see if I can find earlier census returns for you.
There's a marriage of an Emily Davison to a William Richard Carter in 1889 Barton I district, I'll try to find Emily in 1891 and 1901, may throw up some more clues for you
