Thanks for your reply.
I am related to the Rossiters but not Olive's line so we're not related. I am just researching the Rossiter family tree generally out of interest.
I have a database of over 20,000 Rossiters and their spouses and was able to identify Olive from what you had posted.
Are you descended from Albert Frank or John?
Do you have any information about Olive that might help e.g.an older brother or sister born pre 1901 or perhaps Olive's marriage or birth certificate which would list her father's name?
As for getting more Castein information have you tried posting here:-http://genforum.genealogy.com/hollandcountry/
You could also try this site:-http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi
Type in the surname Castein and see the entries that come up.
I'd appreciate any information you have about Olive and general birth/marriage/death statistical information about her children.
Can't contact you via Ancestry as I am not a member. Do you have a direct e-mail please?
Hope you can help.
