35 is rather late for a first marriage - was she married before or are your dates queriable ?
German included Peel which was a fishing port with reasonably strong links to Ireland - Irish links were also formed via 1798 irish rebellion and the Manx fencibles stay around Omagh

I also have an 1814 census of heads of household in Peel - will see if any Wilson family on it. (It will appear sometime on my web site!)
