I earlier mentioned PIONEER MILLERS of SA & had to run my friend to the airport so I didn't finish my post.
The Current Pioneer Mills is a successor organization of the community-owned grist mill that was founded 300 years ago on the San Antonio River. - The current company still has the grinding wheels & parts of the allied equipment used to grind meal/flour that the Canary Islanders used 300 years ago.
(San Antonio was actually settled by the Canary Islanders who were "volunteered" by the King of Spain to settle this area of what is now Texas.)
The more that I learn about the ethic geography of Bexar County/San Antonio, the more that I realize that I don't know. = The ethnic history of this area of Texas is at a minimum "complicated", with lots of twists & turns to confuse researchers.
A simplified (but mostly correct) ethnic history of this area is:
1. A hunter-gather culture until the mid-16th Century,
2. Then the Spanish army & the Catholic missionaries moved in & most of the NA left,
3. Then about 3 decades later the Canary Islanders comprised about 75% of the population,
4. Then the "Americanos" started moving in about 1810,
5. After the area became part of the USA in 1845, the Germans & Swiss arrived and for almost a century San Antonio was a MAJORITY German/Swiss city.
6. Then the Eastern European immigrants arrived & the Germans moved north to found "new all-German/Swiss towns" like New Braunfels, Kerrville, Giddings, New Berlin & Shulenberg.
7. Then the Eastern Europeans moved North to found towns like West, Kiev, Moscow & New Bohemia.
8. Then for another 40 years the area was predominately Tejano.
and
9. After about 1880, the city became the polyglot & colorful mixture of every imaginable group, as it is in 2016. - In 2016, Bexar County is about 55% "Spanish surnamed" but presuming that those 55% are actually Spanish/Tejano is a gross & misleading simplification.
(As one example, my good friend Adolpho Jesus Castro de Palma, of Southside SA, calls his large extended family "Tejano-Spanish" but his ancestral tree includes Apaches, Czechs, Sub-Saharan Africans, Scots, Germans, Russian Jews, Basques, Canary Islanders, Irish & likely other groups. = I chuckle to myself when he says, "We are pure Spanish & Apache, clear back to the 1600s." = His "middle son", Steve, has looked up the last 10 generations of their family history & it is as complicated as the history of San Antonio/Bexar county.)
Each of those ethic/racial groups "left their stamp upon" the city/county & in particular upon what we now call "South Texas food" where a person, in a 15 minute drive, can have sauerbraten tacos, Lithuanian/Tejano chorizo, Basque-style enchiladas & Pan-Asian chili con carne. - One large local café advertises that they "specialize" in Thai-Tejano foods.
(Is that "confusing" enough for you?)
