Joshua M. Rosenblum

A 'Keeper' for Little Zoe
Two weeks before Joshua M. Rosenblum's and Gina Hawryluk's Sept. 15 wedding date, the couple rented a dinghy in Point Pleasant, N.J., and took Ms. Hawryluk's 5-year- old daughter, Zoe, crabbing.

At first the crabs they found were too small. Then Zoe caught one, and Mr. Rosenblum pronounced it big enough to keep. "Zoe threw up her arms and said, 'I got a keeper!' and his face was like a proud father," Ms. Hawryluk said. "I will always remember the look on his face. He was so sweet and gentle."

Mr. Rosenblum, 28, met Ms. Hawryluk at Cantor Fitzgerald, where he was an assistant trader and she was a trader, and three years ago Mr. Rosenblum moved in with Ms. Hawryluk and Zoe at their home in Hoboken, N.J. "When you think of your kid, sometimes you can't envision them as a parent," said Susan Rosenblum, Mr. Rosenblum's mother. "But he adored that child and it was just as clear Zoe adored him. She called him 'my Josh.' "

On Sept. 11, Ms. Hawryluk stayed home from Cantor Fitzgerald to make the final preparations for the big day. But Mr. Rosenblum went into work, intending to put in one last shift before his wedding.
