Adding a sibling when parents are unknown

[comefromaway]

Hello, I'm a very occasional user (of Reunion, that is) so this may be obvious to most, but I can't figure out how to add siblings of my g-grandmother, as I don't have any info on her parents (to add their children). There isn't an 'Add sibling' option in the flyout. Any suggestions? Thank you in advance.

Simple: Add an unknown father as ? Smith, unknown Smith, or some such. Then you can add a child.

Thanks, I guess that would do, but seems a clumsy solution for a fairly elegant piece of software. I think I'll add it to Suggestions.
