Graphics, Figures & Tables ⇒ Help in making a family tree using TikZ

[mavenuparker]

Hey I'm planning to create a family tree similar to the Family Tree at TeXample but it is a horizontally expanding one.

I want to create a vertically expanding table. And also the spouse should exactly below the Parent/child/Grand child.

I'm new to this TikZ package.
Your help will be highly appreciated. Thanks in advance.
