My g-grandfather, Albert Bernhart NIELSEN (1868-1943), was born in Aeroskobing, Svendborg, Denmark, and emigrated to San Francisco, CA around 1890. His father was Anders Bernhart NIELSEN, born on 16-Dec-1837 in Copenhagen. Looking for more info on Anders, when and where he died, and more importantly, the name of his wife (my g-g-grandmother). Any research suggestions? Thanks!
