Hello,Obtaining death certificate of her or of Gottlieb and Louisa should provide some info or have you tried the Cemetery records?As you say they are from Pasewalk Germany I would imagine to obtain Gottliebs and Louisa's Marriage or Birth records you would probably need to e-mail Mecklenburg Archives as I think the records would be there as Germany has all separate BDM records in each area not like Australia.I think Birth records only recorded Mecklenburg after Ottilie's birth date so would be Baptism parish record only I imagine.However if Gottlieb and Louise were Married there then there would be a record.Also I would imagine as you know Ship you have checked Ancestry Hamburg immigration records that has Gottlieb's arrival.Rgds
