Maria, here are the details from the marriage cert. of George and Annie..
December 25th 1897 at St James Church Bermondsey, George Carvallo Lowther age 22 a Drover living at 25 Salisbury Street married Annie Elizabeth Lyons also age 22 from 19 Salisbury Street - his father George Lowther a Drover, her father Jeremiah Lyons Labourer
Witnesses Francis Nicholls and Mary Burns.
I've not been able to find any further info on the Lyons side of the family, although my Lyons notes say 2008 so time for another look around

The witness Mary Burns was George's cousin.
Thank you for the extra info re deaths. It's no surprise to me when you talk about domestic violence, I've heard it said about other male members of the family. I think they were victims of their time, hard drinking, poor living conditions and violence seemed to go hand in hand, the women of the family did seem to get a pretty raw deal !
How exciting! a trip to Madeira, hope you have a great time and good weather.
