I can't see a marriage for James and Priscilla but several sites do list her suname as Penfold . In 1881 Priscilla's birthplace is listed as Portsmouth so a possible in 1871 at Near Seaway Lane, Abbotsbury, Weymouth, Dorset

Looking at this site I previously posted James Penford and his wife Priscilla Penford were cousins. Gets confusing with so many Priscillas
