Hi Ken, I took a look on Lancashirebmd and found her birth. Then I looked at possible marriages in Wigan and there are two for a Rachel Ashurst, one at St. Catharine's in Wigan in 1871 and the other at St. David's Haigh in Wigan in 1877. Don't know if either of those sound right. Unfortunately, I couldn't see any for Upholland. R.
ps. there was one at St. John's Pemberton in 1906 but though that was a little late although Pemberton is not that far from Upholland.
