I decided that if I don't hear from my cousin about my mother's death, that I would contact my aunt (her sister).
I just googled my aunt's and her husband's name and found his obituary and it seems that they were no longer married. So still missing the information that I need to locate my aunt.
Although I don't have contact with my sister, I still miss knowing about her and her life, especially the news about my nephews, ie. is she a grandmother, yet?
I don't call my brother now, but I know whom to call if I want an up-date on him. I just miss the way it was before his health went downhill.
