To what extent did Virginia Woolf's family influence her depiction of families in her novels?

In many of Virginia Woolf's novels (such as "The Voyage Out", "Night and Day", "Mrs Dalloway", "To the Lighthouse" and "The Years"), the concept of family, and in particular family breakdown, appears. Considering her own life (her parents, brother, and half-sister all died when she was relatively young), does her family influence this portrayal of families? Obviously, one would have to give biographical information about Woolf and a description of the principle families in some of the novels (Mr and Mrs Ramsay in "To the Lighthouse", the Dalloways in "The Voyage Out" and "Mrs Dalloway", etc.)
