It depends what namespace "Grandfather Clock" is in. If it's in a different namespace, you need to use a wiki link BB-Code (see your Special:WikiCodeList). If it's in the same namespace, the wiki might automatically make the partial "Grandfather Clock" a link.
If you click on the BB-Code in the editor you may notice that it doesn't ask for an option. However, it does accept one.
In this scenario, you want to link the full phrase to an article "Grandfather Clock". Put "Grandfather Clock" as the option-code of the BB-Code.
Code:
[bbcode="Grandfather Clock"]Grandfather Clock 1902[/bbcode]
