Creating Relationships (Spouse, Children, Partner, etc)

Is there a simple way in Zoho CRM to create relationships similiar to Salesforce. IN salesforce you can create a relationship between two contacts. This is a useful way of tracking children, spouse, etc.

Or, if this is not possible, how could I create a custom field that relates to a two or three other fields. Example. First, Select Relationship (Like Spouse), then have spouse have a name and birthdate field.

After this how could I add multiple relationships to one contact? A one to many relationship.

Thanks.
