Thank you for your comment Richard.
Unfortunately I think there is little I can do from the Appearance • Widget area.
What I am attempting to accomplish is to physically move the Sidebar to a location further down the page.
When I Activate the Twentyten theme, the Sidebar is in a place that would nearly work out ok.
When I Activate my Child theme, it jumps up to the top.
Having said that, I have adjusted some of the Child CSS properties to bring the Sidebar down, however when I do this, it (the Sidebar), disappears behind the page contents where it is non-visible.
Really struggling with this issue so if anyone can assist me with this, I would be truly very appreciative to hear from you.
Many, many thanks in advance for your help!
