To: Listers, I am writing about map 1890 subject for San Francisco. I need exact location where my great grandfather Antonio F. De Escobar and his family´s residence address at 24 Commercial.... Reference: http://www.sfgenealogy.com/sf/sanborn/sanborn.htm I studied at map at first. I was not sure about what 24 means. It looks like a block number for that year of 1890. It was disappearing in late 1900´s because that street is not on some of old maps. There is no 24 on some of old maps, either. I found Commercial St on sheet 14 which is showing 21. So, it means that 21 starts numbers in order like 22, 23, 24.... Am I right? I am little bit confused. Later, I looked at current map again and narrowed down where it is. I finally found Commercial St. nearby Clay St. and Sacramento area. It is showing large numbers* on the list below for Commercial St currently. There is no 24 on Commercial street. I am assuming that 24 is no longer for current street. Was Antonio F. Escobar living on that street currently with his family in 1890´s? http://www.mapquest.com/maps?city=San+Francisco+&state=CA&address=Commercial+St 1. *[400-499] Commercial St San Francisco, CA 94111 * Map * Directions To * Directions From * Search Nearby * Send to Cell * Send to OnStar 2. *[500-552] Commercial St San Francisco, CA 94111 * Map * Directions To * Directions From * Search Nearby * Send to Cell * Send to OnStar 3. *[551-599] Commercial St San Francisco, CA 94111 * Map * Directions To * Directions From * Search Nearby * Send to Cell * Send to OnStar 4. *[600-699] Commercial St San Francisco, CA 94111 * Map * Directions To * Directions From * Search Nearby * Send to Cell * Send to OnStar 5. *[700-799] Commercial St San Francisco, CA 94108 * Map * Directions To * Directions From * Search Nearby * Send to Cell * Send to OnStar I just need feedback.
