can anyone help me find this movie?

[kurgan]

hello guys. trying to find a horror movie i saw years ago and barely remember.
it was about a haunting (i think) in some sort of mansion, the characters founded dryed corpses, including the one of a baby in his cradle .
i do recall the ending; a shot of a coast (urban i think, i pretty sure it had a big ship in it) close to the water level, then a voice says something like "that day something terrible was born" the camera aims down and beneath the surface you see a baby (probably not a very cute one).
i know the info is very obscure and probably distorted over the years, sory for that, but i have been trying for years to find it, so i guess i may ask some horror experts out there.
