Just updating my own research in case another family member comes across this, although this appears to be increasingly unlikely. Perhaps descendants from another Quinn line.
I haven't found a shipping record for him yet, but in 1941 in Brentford, Middlesex James Killeen marries Constance May Bentley (born 1903 in Lambeth). Between 1949 and 1958 James and Constance can be found at the same address in Acton. Over the years they share the house with a rotating cast of names, possibly boarders. In 1958 Constance dies in hospital in Acton.
I haven't found any evidence of James and Constance having children.
In 1960 James is sharing the address in Acton with Winifred E G Lewis, Frederick G Lewis and ... Doreen M Lovery. Back tracking to 1959, Winifred, Frederick and Doreen can be found at an address in Wembley. In 1962 and 1963, James, Winifred and Frederick share the Acton address with another couple who have lived at various addresses in the area but Doreen has moved on.
A 1960 shipping record shows Doreen Tate-Lovery from the Acton address travelling to Perth, Western Australia. Electoral rolls from the late 1940s and 1950s show Doreen
Mae Tate-Lovery living in Canning Vale, WA with Thomas Patrick Tate-Lovery. Shipping records show the couple travelling to and from Perth together and individually. The State Library of WA has portrait photographs of Thomas and Doreen from 1952.
Thomas Patrick Tate Lovery (no hyphen) is born in Mysore in 1889. In 1940 he marries for the second time in Madras to Doreen Mae
Lewis. Based on the London living arrangements I'm confident this is actually Doreen May Killeen. A related thread here:
http://www.rootschat.com/forum/index.php?topic=712505.0A 1952 WA newspaper item informs that T P Lovery has sold his property. In the 1960s Doreen is living in WA without Thomas, and in 1969 Thomas Patrick Tate-Lovery dies in Hindmarsh, South Australia.
I haven't found any evidence Thomas and Doreen had children or a death for Doreen. There appears to be just one other Tate-Lovery family in Australia that move to Perth in the 1960s and who descend from Thomas' brother. It is not yet clear why Doreen would have married using the name Lewis.
Winfred’s will identifies a niece Patricia Shaw and her husband Anthony Shaw at an address in Hemel Hempstead. A commercial site with relatively recent electoral roll data shows Anthony of that address had the middle initial J. Anthony Joseph Shaw and Kathleen Patricia Kelly marry in Calcutta in 1946, showing the age of both as 30. On several shipping records between India and England, (Kathleen) Patricia shows a birth date of 1918. Kathleen Patricia Shaw dies in Hertfordshire in 1998 with the death index revealing a birth date of 1913. Anthony Joseph Shaw dies in Hertfordshire in 2003. Shipping records also include a daughter Patricia Ann Shaw born in 1948 probably in India. Patricia Ann Shaw dies in Hertfordshire in 1964 aged 15. This partially answers the question of whether this family line survived to my generation as Patricia Ann would have been my 4th cousin.
Patricia Ann, Kathleen Patricia, Anthony and Winifred (indexed on deceasedonline as “George aka Winifred Edith”) are all buried in Woodwells Cemetery. Winifred is buried alone, but Patricia Ann, Kathleen Patricia and Anthony are each shown as sharing their grave with one other, suggesting there is one more burial to discover next time I have credits on deceasedonline. Having a half-sister, niece and grand-niece that die in Hertfordshire supports the suggestion that the James A Killeen that dies in Hemel Hempstead in 1964 is James Austin Killeen.
Kathleen Patricia Kelly’s birth date of 1913 along with her forename suggests her mother might be Kathleen Mary Killeen born 1893 although Aileen Margaret Killeen born 1896 is not entirely out of the question. I have not found a marriage of a man named Kelly to either Kathleen or Aileen Killeen. I have no other leads on the fate of Kathleen or Aileen Killeen.
Of course, most of this has taken me out of "Other Countries", however I still have no other leads on the fate of Kathleen or Aileen Killeen.
Edit: Date of property sale.
