I am researching the family tree of Herman Roelof and Antionette Marie (nee Mulder) ROSENBOOM. They had 2 sons, Gerardus Johannes ROSENBOOM and Herman ROSENBOOM and 1 daughter Marie ROSENBOOM. I know that they lived in Amsterdam. Gerardus and his family migrated to Australia in 1954. I have information concerning this family and would like to hear from any-one with any information concerning the families of Herman and Marie.
