Show parent with children

Greetings,

Using WP as CMS, I have created a block that appears on each child page and lists all “siblings” under that parent. Thus if you go to the Sacramento page you will see on the right the sub topics for Sacramento. Easier to see than explain:

https://www.detailsca.com/wpress/?page_id=13

Where I am stuck: I need that block to list the parent as a heading. (in the example, it needs to say Sacramento over the bulleted News item in the grey square) Otherwise, if you click on News, say, the news page itself does not tell you what city you are under. I’m a fiddler and copy/paster and I’m at the end of my limited resources.

Any suggestions will be much appreciated!
