Thank you for your replies. I have the entire article and it definitely states "On July 27, at 2 Arkwright Street, to Ivy (nee Everett), the wife of Leslie Dence, of 11 H.H.M." At 2 Arkwright Street suggests a home birth so something military related does make sense. Unfortunately, I have found neither military records for Leslie Dence (born 1917), nor this abbreviation. Any help appreciated. Thank you.
Best regards
Christine
