Per https://twitter.com/JaneEspenson/status/527564236507979776, Sara's Ice Cream (http://onceuponatime.wikia.com/wiki/File:109ComeOn.png) is NOT Ingrid's shop. So I guess that Ingrid may not of entered Storybrooke as early as I initially speculated. She might of entered Storybrooke after being Emma's Foster mom.

Also, I suspect that Ingrid did some ID theft (or worse) in Boston and assumed the Alias\persona of 'Sara Fisher'.
