[40K] Are there any Space Marine Inquisitors in M41?

The story goes that 8 of the 12 founding members of the Inquisition were Astarte. As much as I've read through Lexicanum, I've never encountered Space Marine Inquisitors after the founding of Inquisition.

A Space Marine is a 2 metre tall superhuman with acid spit and muscles so big it makes it hard to enter buildings without smashing the doorway. The inquisition is a secret police force that hunts the Emperor's enemies through the shadows. Space Marines don't fit this style of operation, and they're also too valuable to waste on softly-softly investigation anyway.

Some inquisitors keep close ties to the Space Marine chapters, as 1000 supermen make a good friend but marines marines will never join the inquisition. Unless  there's one left from the chapter again, as was the case during the Founding.
