My wife's late mother's maiden name was Stratford, and she was born in Co.Cavan, Ireland. I note you are now living in Ireland. If you are anywhere near Finnea (W.Meath?), there is an old, disused churchyard at Drumlummon, where a number of Stratford ancestors are buried. Several of the graves there have the Stratford crest on the headstones, - the crest is a lion rampant on a background of ten horizontal bars, under an armoured arm bearing a sword. The motto is: "VIRTUTI NIHIL OBSTAT ET ARMIS", (Nothing withstands virtue and arms). This is the same crest as used by the original Irish Stratfords of Baltinglass, Co. Wicklow, who bore the titles Viscount Amiens and Earl of Aldeborough. If it would be of use to you, I can e-mail notes we made at the Drumlummon chuchyard. Hope this information helps you.
Best Wishes, Mike
