Thank you Jean for the info; re Elizabeth's son, William
Elizabeth's marriage to William Towsend pre-dated the 1849 Marriage Act and their age - occupation -address - and their father's name and occupation are not shown on the Marriage Certificate.
I am assuming that she found employment & a husband while working in a hotel or a boarding house in Douglas. As did two of her sisters - Jane (Kelly) & Leonora (Terry).
William Townsend/Townend was a brazier and I assume he came to the I.O.M. to work in Gelling's Foundary, Douglas. Unfortunately the records of the workmen do not go back that far.
Thank you for adding some more 'leaves' to the tree. Harry
