Who is Annie R?

Here's what I currently know to be true about Annie R:

• In the 1901 Census, she is listed as the wife of Harry Martin (b. about Dec 1850 in Bosham)
• In 1901, her birth is recorded as 1853 in Bosham, Sussex.
• Before 'marrying' Annie R, Harry was married to Frances Marsh, the last child was born in 1890
• In the 1891 Census, Frances Marsh is listed as the wife of Harry Martin.
• I have been unable to identify a marriage record for Annie R and Harry.

In the Bosham Parish Register, there is a marriage listed for a widowed Annie Rosina Martin and George Brown, also widowed. Annie's father is shown as George Purver, a baker.

Could this be Annie R?
