Hi Stewie,
Awfy kind of you to be so understanding! Must be that good nature you possess

Here are 1881 censuses for 2 of William LAWRIE & Sophia WHANNEL's children.
(i'll
not give the outside chances for Robert & Daniel - i've made enough bloomers already!)
By the way, the IGI has 3 children (William & Sophia were in Helensburgh in the mid 1850s).
As was William's mother Mary IRVINE, but still can't find her in 1851.
