Miriam and her mother had selected April 30 as an appropriate wedding date, especially since Miriam would turn 21 on April 15, and April was her mother's favorite month.  Michael and Miriam checked with their pastors in Springfield and Hoboken, both of whom indicated difficulty in getting the banns published and expediting the marriage for April.  Father Edward Kroyak, a young priest-friend, jokingly suggested to Michael that under the circumstances with an office in New York City, he should try for St. Patrick's Cathedral and, if Michael and Miriam would like this, Fr. Kroyak would get to work on the necessary paperwork immediately, which he did, and successfully.  Michael and Miriam were married in Our Lady's Chapel, St. Patrick's Cathedral, New York City, with their families and Monsanto's New York Office in attendance.  After a short camping honeymoon trip in upstate New York and Canada, Michael and Miriam, with Michael Jr. and Chalice, took up residence in a downtown Cincinnati hotel; Valerie went up to Springfield to stay with the Coombs.

Monsanto St. Louis Corporate Real Estate Managers had selected an abandoned U.S. Cast Iron Pipe & Foundry site in Addiston, Ohio, at the north end of Cincinnati's Ohio River strip, with the Little Miami River as boundary.  The Texas Monomers Division wanted a river port and this site was chosen for both the new Plastics Division Midwest plant and the monomers division river port' and Gigliotti was named the Project Construction/temporary Site Manager for both projects.

In 1951 Michael selected Penker Construction as the General Contractor, Monsanto selected a bank, established a large line of credit available to Michael plus one other signature as the checkbook for the entire project.  The family that had owned and operated the U.S. Cast Iron Pipe and Foundry Company had a plot of land on the other side of the Little Miami River, in the Fernbank district of Cincinnati.  On this plot of land they had built four substantial brick homes, three of which had been sold outside the family, one of which remained unoccupied within the property of U.S. Cast Iron Pipe.  Miriam picked this to be their future home and immediately set about clearing it out and filling it with old and new furniture.  The only electricity in this house was in the kitchen; the upstairs bedroom and the downstairs living rooms had gas fireplaces and gas lamps, and the central heating was a huge hot air coal-fired furnace in the basement, which sent hot air into the house through a large grill in the central hallway.  Michael arranged for electricity to be put into each room via outside wiring with an outlet in each room under the window.  Son Edward was born in Cincinnati in 1952.
