Lovendale family from Norway and Sweden

Hi all, I am new to this site..and searching passenger records for my John Lovendale/Lovendahl family . I have a found a family that arrvied in Boston on the Cephalonia July 30, 1888. This steamer left from Liverpool. Christine Lovendal, mother childen: Helena, Amanda, Alma and my Grandfather, John. My Grandfather was born in Norway, all the others were born in Sweden. My Grandmother, Ida Christine Boman Lovendal was married to John Conrad Lovendal, I believe. My family has always spelled this surname as Lovendale here in the U.S. I would appreciate any help I might have! Betsy in Maine
