They came via Suffolk, so a smaller step to begin with perhaps.
Elsie's father, John Henry, was the son of a Nicholas Mouzer b1846 Wolverton (& Ann Hughes), who was the son of James Mouzer b1810 Walpole, Suffolk (& Harriet Masterson), son of William Mowser b1773 Huntingfield, Suffolk? (& Lucy Cull), son of William & Hannah maybe.
There are many still around that area on the 1841 census.
