Subject: Can we construct free semi-lattice from free dist. lattice?

Dear All,
I have a problem which I had thought very specialised, but actually can be
stated very generally: -
I have a category C with finite limits, and so I also have a category
DLat(C) of distributive lattices which, lets say, has coequalizers. If free
distibrutive lattices can be constructed (i.e. if there exists F:C->DLat(C)
left adjoint to the forgetful functor) then do free semilattices exist?
Thanks, Christopher Townsend (OU)
