Oskarshamn Kvarteret 421A

[Gwen Stuler]

I am working in AD Oskarshamn AIIb:2  (1900-1907) Image 98, page 664 (AID:v198472.b98.s664, NAD:SE/VALA/00293.  
My gr-gr grandmother, Vendla Larsson b. 1837, owned this building/house at this time.  
1. Were all the people listed on this form renters? Was 421A an apartment or does 421A refer to a large quarter within the town?
 
2.  If the people listed lived here, then how was Household Exam conducted during that time....by a large geograaphical area?
3. Does anyone know how I can get more information on how the town of Oskarshamn was organized or layed out during the late 1800's to early 1900's.
 
Thanks in advance
