Hi Osborn,
Emma is still in Devon in 1901, aged 44, married to Frederick aged 39.
Your Emma Eveleigh is shown as a spinster aged 34 on the marriage certificate to Joseph Baptist so I am pretty sure they are two different people.
Your Emma is a Lodger at 12 Westmoreland Place, London in 1901, born Tower Hill London ca. 1862, a general servant (domestic).
