If family and ancestors really, really matter, you can dig up a corpse and manufacture an ancestor.
Ritual ghost marriages, which may date back to the 17th century BC, are increasingly rare in contemporary China – Mao Zedong tried to eliminate them when he assumed power in 1949 – but they are still practised in rural parts of Shaanxi, Shanxi, Henan, Hebei and Guangdong provinces. Families often employ a matchmaker to help find a suitable spouse for their deceased loved ones.
Bet they never dig up dead grooms.
Somehow, I suspect not.
