The Omaha city directory for 1939, found by Kristen on Ancestry.com, verifies the status of the Tillotsons. From these pages it emerges that Tillotson Contruction Company kept offices at 720 Grain Exchange Building. Joseph H. Tillotson was president, Reginald O. Tillotson was vice-president, and their mother Rose A. (Brennan) Tillotson was secretary-treasurer in this  year.“Grain elev,” as seen in the listing, would refer to the company’s specialty.

Company president Joe Tillotson appears to have lived at 345 N. 41 St. with his wife Sylvia.

For the other Tillotsons, what could be a residential address of 1804 Dodge St. is given, although the directory’s abbreviations aren’t clear. Included here are Mrs. C.H. (Rose) Tillotson, who was by then the widow of Charles H. Tillotson, and Mary Tillotson, Reginald’s sister.

It seems unlikely that Reginald lived with his mother and sister at 1804 Dodge St. because by 1939 he and his wife Margaret already had at least four children of their own.

All this is in keeping with the announcement the previous autumn of Tillotson Construction Company’s establishment.
