Jenny Brown is still out there. Now a 48-year-old mother with two sons and four grandchildren — with a fifth grandchild due this week — Jenny Brown still lives in Jonesport, almost 37 years after she sent a message in a bottle from there that was discovered on Cape Cod two weeks ago, according to her sister, Kathy Brown. The Browns expressed surprise at how they have been bombarded with social media messages and telephone calls since a BDN story published Monday night reported that Joshua Mendes, a 48-year-old grocery store clerk, discovered the Coke bottle while beachcombing in Provincetown, Massachusetts, two days before Thanksgiving. Dated May 14, 1983, the note listed a Jonesport post office box and had a simple message: “Please write me.” Jenny Brown said she remembered sending the message in a bottle but only spoke briefly to Mendes’ father, Paul Mendes, on Tuesday.
