Did you get an answer concerning Main High School in San Antonio ca 1918? It is possible that Los Angeles Public Library (5th & Flower) in its history/genealogy department has city directories for San Antonio (possibly for all of Bexar Co., TX) for the years you are interested in. (A city directory is NOT a telephone directory. It lists, in general, all the employed folks in a city with their addresses, and their occupations. Then in the backs of some of the later ones, is a reverse directory. This part of the directory will frequently list the address of the residence (perhaps of a business, I do not recall) and then it may list ALL the adults at that residence!!! I found a widowed mother living with her employed son by using the reverse directory.) Such a directory will be full of ads for all kinds of businesses. Incidentally, in the *old* San Antonio Public Library (on the River) there were many city directories for San Antonio, and I spotted my great-grandfather, who had been a blacksmith for many years in San Antonio prior to World War I. The college to which you refer in Denton (College of Industrial Arts) I believe became what is now called Texas Woman's University (formerly Texas State College for Women). I imagine TWU has a website these days. Then you might ask about Archives or a reference librarian or a historian. (An acquaintance of mine was doing some research on a long-ago relative who attended Notre Dame U. in Indiana. She wrote to the Archivist and got some valuable info--who paid his tuition, etc.) Since TWU, unlike Notre Dame, is a public institution and may not have all the papers one might think they should have, you may have to do a LOT of inquiring!!! While helping a lady with Denton relatives, I found out that there is a Denton [county?] Genealogical Society. As for Main High School, I believe later it may have been called Breckenridge High School [perhaps with an a instead of an e] High school. It is possible that the Texana desk at the San Antonio Public Library (the big one on Soledad Street) may be able to tell you about that. I must say, if your remale relative went to college at that time period, she was one of the privileged females in Texas!!! When I was caught in a blue norther in Texas one spring several years ago, I ducked into the Daughters of the Republic of Texas library (on the grounds of the Alamo) and had a ball going through their card catalog (long before personal computers were so prevalent and online catalogs were only at well-endowed Universities). I glanced over at one of the bookshelves and noted that they had a collection of school yearbooks. I did not examine them. I imagine they had been donated by members of the Daughters of the Republic of Texas. I doubt that TWU was represented in those yearbooks. However, perhaps TWU library has some old yearbooks.
