As a follow up to initial research made on Edward Crawcour son of Isaac Crawcour and Simha Cohen De Lara I have discovered his second 'marriage' to C ( first name unknown at present) Ward. Ward is her married name.
Edward Crawcour was married first to Margaret Buchanan and they had 2 children: John Isaac and Helen ( Ellen) Semira.
In the 1851 Census H0107/1869 ( Crown Copyright, care of TNA)
Edward is living with his first family and step children at 30 Southam way Exeter Devon:
E C Cartwright Head M 43 proprietor of houses b Middx London
C I Cartwright wife 51 b Lanac...... ( difficult to decipher)
John Cartwright son U 16 scholar b Philadelphia America
Ellen Cartwright dau U 15 scholar b Hull Yorkshire
Jane Ward dau in law U 23 b Shropshire ( difficult to decipher)
George Ward son in law U 19 Mechanic b Bengal India
William Ward son in law U 17 b ? Belaphore India
George Ward appears in the 1881 and 1891 census as a dentist and William maybe the stockbroker recorded in the 1871 and 1891 census as born Bengal India.

I can find no record on FreeBMD of a marriage by Edward using either Crawcour or Cartwright to anyone named Ward.
Any help locating his 2nd 'wife' appreciated.
