Hi Len,

I looked at this marriage, but she wasn't underage:
29 Dec 1877
William QUAYLE Full age Bachelor Tailor Maughold, [father] John Quayle, Labourer, and
Jane KERMEEN Full age Spinster Maughold [father] John Kermeen, Labourer.

This looks like Jane Victoria, dau of John Kermeen & Ann Kermeen bapt Maughold 22 Dec 1839.

1881 census from Familysearch:
William QUAYLE Head M Male 38 Andreas, Brick Maker
Jane QUAYLE Wife M Female 40 Maughold, Wife
William QUAYLE Son Male 11 Andreas, Scholar
Eadth QUAYLE Daur Female 9 Andreas, Scholar
Jessie (Lissey) QUAYLE Daur Female 4 Andreas

Doug, are these the William and Jane you are looking for? The dates are nowhere near what you wrote, but if this is the same couple who married in 1877 William appears to have children from an earlier marriage (although bachelor in 1877 marriage), or they had children pre-marriage. Son William could be in the IGI as William James Quayle bapt 03 OCT 1869 Andreas son of William Quayle & Jane "KINACH".
The IGI also has a Jessie aged 4 as bapt 6 JAN 1878 Maughold and "Death: 06 MAR 1881" which was before the census was taken! So she can't be the one with the above couple in 1881.
The Maughold register has the burial of this Jessie QUAYLE aged 3 yrs as from Douglas.
Jessie daur of William Quayle & Jane Kermeen bapt Maughold Parish Church 6 Jan 1878.

The IGI has Elizabeth Jane Leah Quayle Birth: 11 JAN 1880 Douglas Father: William Henry Quayle Mother: Jane Kerneen Quayle, which says it is an extracted record but has no source (extracted from where?).

All very confusing.

Doug, what were her death cert details "died on 4 May 1936"?
