Can anyone help with family tree?

CAN any of your readers help me bring my family tree forward?

My grandmother's name was Ivy Peacock before she married my grandfather Frederick George Stanley. Both died before 1990; until the 1960s they lived at 1 Wyevenhoe Road, Harrow.

Ivy had several siblings and step siblings; Eliza Miller married an E Kemp and had several children (no need to find out more of these).

There was a Robert F Miller (aged 25, 1911 census); Edward Peacock (aged 15, 1911 census, and a signatory at Joy's wedding in 1921/2); William Peacock (aged 17, 1911 census); and a Samuel Miller. I believe there is a connection with the railway for Samuel and Robert.

I've been told two of the family died during the First World War but know no more. If anyone can help I would be grateful.

The majority of the family was living at 97 Mayo Road, Willesden, Middlesex, according to the 1911 census.
