Edenvale Lodge, where Jennie was born, was presumably a nursing home as the family's address at the time was 34 Bachelors Walk, Dublin.
In her early twenties Jennie became pregnant but because she was unmarried she went to London to avoid scandal, staying with relatives there until the baby - a boy - was born. Jennie returned to Dublin after the birth, leaving her son in the care of an elderly aunt (identity unknown). When Jennie's son was about six the aunt's health deteriorated and he spent the rest of his childhood in foster care. He later married and had two daughters. Some years later (possibly in 1949) Jennie married John Hannigan; they had no children.
Jennie inherited the family musical instrument business from her father as a cutting in a family scrapbook of a newspaper advertisement shows. Neither the name of the newspaper nor the exact date of the advertisement is known but it probably dates from the 1920s or 1930s. It reads:
(Successor to G. BUTLER & SONS)
Being the 5th generation in direct line trading in Dublin since the rebellion of 1798
Everything Musical from BUTLER'S
Is a "SOUND" investment for Bands or Home use
State Instruments, Spares or Repairs
Contractor by Appointment to the NATIONAL, BRITISH and BELGIAN ARMIES
2 LR. ABBEY ST., DUBLIN
(Opposite Wynn's Hotel)
I had been told that the Butler musical instrument business closed due to financial difficulties in 1927, but the company was still advertising in national newspapers up to at least 7 September 1931. Furthermore, a newspaper clipping in the family scrapbook, dated 21 November 1933 (publication unknown), tells us that "The firm of Messrs. J. Butler...is still being carried on at 2 Lr. Abbey St., although the head of the firm, Mr. W. J. Butler, died a few weeks ago". It could be that the company had ceased manufacturing in 1927 but continued as a shop. The business finally closed in 1941.
