Have a Anthony Bracchi/Brackey/Braky born abt 1824 Italy marries in 1846 Shropshire to a Mary Ann Shaw born according to the 1861 census in Leicestershire cannot find her or the oldest two children in 1851 ,if anybody has the time to look for them.

They have at least 9 children

John 1846
Francis 1850
Joseph 1852
Louis 1855
Mary 1857
Susanna 1859
Sara 1862
Anthonius 1864
Sara Philomena 1867


all baptised in St Werburgh's Chester Cheshire

Question is why on some does it say the Mother's name Shaw or Reilly/Reily/Riley, I am assuming Reilly is her single name ? and if so I cannot find a marriage for her to a Shaw? she would have been a bit young to have married before.

Thanks
