The Ulster Covenant - Dublin signatures

In trying to trace members of the "Loyal Dublin Volunteers", a Dublin affiliate of the Ulster Volunteer Force, I've had a look at the Ulster Covenant and Declaration database available to view from the PRONI website. The Covenant was signed by men; the Declaration by women.

A search selecting the Parliamentary Division Dublin produces a list of 768. All women. Not a single male signature. Very odd.

A search with Not Recorded for Parliamentary Division gives 1 Dublin address,

H Brown 57 Percy Place, Dublin

The At Sea entry for Parliamentary Division gives a return for Thomas Gee of Rathgar aboard ship.

In the 1911 census, there is a 13year old Herbert Brown living in Percy Place. Surely not the signatory of the Ulster Covenant?

The signatures of the ladies are a bit inflated with multiple signings and with addresses from outside Dublin e.g.

Ethel Hamilton Wilson gives signs 5 times with addresses in Dublin,  Derry, Belfast, Lurgan and Co Down.

Edith Alexander's address is Derry.

Sarah Apsley's address is Co Antrim

Sarah Jane Armstrong's address is Co Fermanagh

and so on, reducing the actual number of Dublin signatures further.

Why so low? What's happened to the signatures of Dublin men?

A recent leaflet expounding the "Loyal Dublin Volunteers", gives the number of Protestants in the County and City of Dublin as over 100,000. The Loyal Dublin Volunteers was supposed to have had a membership of 2,000 men.

Thankfully, not all Protestants were Unionists and and there were attempts to protest against "the lawless policy of Carsonism".
