Can't understand the "too many entries etc"
There is only one entry for Mary K Harmes b 1917 - september qtr 1917 Basford 7b 471 mmn Willatt
Only one marriage between a male Harmes & a female Willatt - 1915 Eastbourne. Arthur E to Helen
Re 1901 & 1911 entries - they were not married at that time so you need to look for them singly. Freebmd has Helen Willatt b 1888 Basford & Arthur E Harmes 1889 Brighton
