This qualitative study examined the experiences of 25 parents who were estranged from their adult children in later life. Most participants experienced estrangement as an unanticipated, unchosen, and chronic loss for which they felt ill prepared. Most described a traumatic loss, ambiguous because of its uncertainty and inconclusiveness, and disenfranchised by societal ideologies embedded in constructs of parenting and motherhood as essential, natural, and universal. Many participants said they were subjected to the social stigma associated with tainted or devalued parenthood. In many cases, the gendered stigma accompanying estrangement positioned the female participants precariously for social rejection.
