Geni is tied in with TreeSeek, which specializes in creating family tree charts. Perhaps that will solve your issue.
Please let us know if it worked.
The site seems to be set up for a maximum 10 generations.
I do not know how far it fans out.
When I tried my family, it branched out to both Maternal and Paternal ancestors, but no siblings, and descendants. The "Cloud" tree is cool as a family logo.
On the "About" tab there are the following links, maybe you could email them for assistance.
