Hence, calling routines should always strip REL_SIBLING and REL_FAM_INLAW_PREFIX before calling get_single_relationship_string() Note that only_birth=False, means that in the reltocommon one of the NOTBIRTH specifiers is present. The REL_FAM identifiers mean that the relation is not via a common ancestor, but via a common family (note that that is not possible for direct descendants or direct ancestors!). If the relation to one of the parents in that common family is by birth, then 'only_birth' is not set to False.
