Hi George in MA, According to The Indianapolis Star, 20 Nov 1914, pg.1 "Louis Hollweg, proprietor of the firm of Hollweg & Reese, wholesale china and glassware dealers, will retire from the firm on Jan. 1, and will divide his stock among a number of his old and trusted employes.... Mr. Hollweg is one of the pioneer busi- ness men of Indianapolis.... also has an interest in the wholesale dry goods firm of Hibben, Hollweg & Co. He will retain his connection with this firm....... Mr. Hollweg will spend most of his time at his residence, 963 North Meridian street... It is a long article with lots more detail but as you can see, he as alive at this date. According to the Crown Hill Cemetery website there are two Louis Hollweg's, presumably father and son. One was buried 8/26/1925 and the other 7/8/1930. I don't have any more time, at the moment to do any more than that. Hope that helps, - Ed
