You left out some important info - when did this family immigrate to the US???
1930 is the last available census at this time. This family does not appear in the 1930 census anywhere.
For military records try - Military Records = This is a FREE service! On line form allows you to request information from your, or your relative's, military personnel record.This option is only available if you are the veteran or next of kin (surviving spouse that has not remarried, father, mother, son, daughter, sister, or brother). Otherwise you will need to send in the SF180.
