”
There is a published tree which shows this couple in 1911. You have John Valente with Annie in 1911.
Nancy can be a "pet" name for Anne.
Nancy who married John in 1905 may be Anne Valente on 1911 census.
Anne was 24 on 1911 census which almost fits with Nancy Pelosi who was aged 15 on 1901 census. A discrepancy is birthplace. Nancy on 1901 census had Italy as birthplace. Anne on 1911 census had birthplace Manchester. However, the source for 1901 is the census enumerator's book, not the original household return. Source for 1911 census is the household return.
Anne had been married 2 years according to 1911 census. The question about length of marriage was how many complete years. So 2 years could have been almost 3. That still doesn't add up to a wedding in 1905 though. 1911 census was taken on 2nd April.
Also in the household headed by John Valente on 1911 census was a man with surname Taylor. Relationship to head of household was servant. Could he have been a relative of Margaret Taylor?
Does 1905 marriage record for John Valente and Nancy Polosi give their addresses and ages? Who were witnesses?
John Valente & Margaret Taylor married on 23rd March 1911. (Date on marriage cert., reply #30)
Are ages of John and Margaret on marriage certificate?
