I learned a few years ago I have a brother. No one knew, my mother gave birth to him in 1959 and immediately gave him up for adoption. My mother died two decades ago so details are hard to come by. My brother worked for years to find us. I'm glad he succeeded! And I feel sad for my mother's story.

I also feel guilty for my initial reaction. A stranger called me out of the blue and told me he was my brother and in that moment it felt wrong. I went with my gut and told him I thought it was a scam. I still feel bad for my rejection. Fortunately he was persistent and talked to other family members and about a year later I got back in touch and we confirmed with a genetic match. Our first talk felt strange because there's no normal way to have that conversation.

My mother never told anyone. She was 21 when she had my brother. She married my father five years later. No one knew about her secret child. Not her sister, not her best friends, not my sister or me. I don't even know if she told my father but I hope she trusted him enough to. Her parents knew but not her grandparents. This secretness makes me so sad for her, she bore this difficult thing without support.

We found a small cache of memorabilia that makes sense now. Mementos from a summer in New York. A letter from Elizabeth Arden (!) saying what a bright young woman my mother was and how nice it was that she visited her health spa in Maine. Just after the birth, I'm curious whether Ms. Arden was a regular host for young women in trouble.

It turns out that unintended pregnancies and complex family trees are way more common than we acknowledge. Ken's family is full of surprise cousins and grandchildren being raised as children. My mother and her generation treated birth out of wedlock as a source of shame. My generation doesn't quite know what to think. With genetic testing now keeping things secret is much, much harder. I feel no shame but even here I'm avoiding names, for privacy.

We know who the birth father is but my brother has been cautious about approaching him, disrupting his life. I would love to know more, he was in my mother's social circle and I would like to imagine young love or at least a summer fling. Instead all I know is the evidence of her shame and suppression.

But now I also know my brother! He's an interesting and successful man and a pleasant part of my life. I'm glad to know him.
