Looking for Ormestad farm in Sandefjord

I visited Sandefjord last week. Thanks to the info that Brining and Eichbache provided me, I now know that my great-great grandparents were August Martin Andersen and Anne Helvig. I visited the Sande kirche and in the graveyard, after searching for about an hour and a half I located their grave. I left a daisy on their stone, in the honor of my great-grandmother Amanda who was their daughter who left Sandefjord for America in 1900 and they never saw her again. I then walked for many kilometers, perhaps 4 or more, to get to the area 'Ormestad'. It appears to be a suburb, with newer homes and flats. Can someone give me a specific as to what farm in Ormestad is where August Martin Andersen and Anne Helvig had their children? And, perhaps tell me where it is located or was located? I am in Berlin today but returning to Oslo tomorrow afternoon and have no plans so I could hop on a train to Sandefjord, it takes about an hour. Sunday I am flying back to the USA so if I could get some info it would be fantastic.
