I don't know if the old newspaper clippings saved by my family might help your research, but they might!These articles are from both Australia and New Zealand, and are from the 1930's:
"JENNINGS MILLIONS" - Distribution Unlikely - Opinion of One of Family (By Telegraph.-Own Correspondent.)
WHANGEREI, this day.
"Mr. Ernest Jennings, of 18, Walton Street, Whangerei, asserts that he is a direct descendant of the late John West, a descendant of the late William Jennings on his wife's side.The family tree goes back eight generations to the eighteenth century.
The father of Mr. Edward Jennings spent a small fortune in attempts to substantiate his claim, but his efforts failed because of the absence of a marriage certificate, which was burnt four generations before, in the demolition of a church in London.Failure to produe the document made an appeal to Chancery useless, and this branch of the family has ceased to entertain hopes of ever securing a part of the huge fortune.
The allocation of the fortune, if the claims were accepted, would be made all the more difficult when it is considered that the original William Jennings married twice, and such a long period has elapsed that there are now many connected with the family who have valid claims.Mr. Ernest Jennings does not wish to be considered a claimant, as he maintains that the money will never be lifted from Chancery.He arrived in Whangarai from England in 1924.He has no knowledge of the Mary Jennings and Miss Sinclair mentioned in a Press message as residing with relatives in Whangarei."

"JENNINGS MILLIONS' - New Zealand Claimants - Two Ladies of Thames. - Daughters of Late Mr. R. Bach. - (by Telegraph. - Own Correspondent.)
"In addition to Mrs. John Barker, of Thames, Mrs. Emily Rowe, of Thames, and Mrs. Howard Strong, of Christchurch, are claimants for shares in the "Jennings millions," now in Chancery.
Mr. William Jennings, whose estate is now said to amount to 53,000,000 (pounds), was one of three brothers who amassed a fortune, and he owned factory sites in Birmingham and a large share in the East India Company.His neice, Miss Mary Jennings, married Mr. William Thomas Malone.Mrs. Malone left 100,000 (pounds)to her husband, who passed it on intact to his five daughters when he died in 1863.
The youngest of the five daughters married Mr. Richard Bach, a prosperous mechanical engineer, of Birmingham, and in 1862, they emigrated with their family of three sons and five daughters to New Zealand.
Mr. Bach died in Auckland in 1877, at the age of 61, after having lost the bulk of his capital in various ventures.The eight members of the family were married.Mrs. Bach, who was a gifted pianist, died at Auckland in 1895.The family in later years consisted, in the order of seniority, of Mrs. Christopher Berry, of Auckland (now deceased), Mrs.F. J. Piesse, Gisborne (deceased), Mrs. John Barker, of Grey Stret, Thames, Mrs. H. T. Rowe, of Kirkwood Street, Thames, and Mrs. Howard Strong, Christchurch, who are still living.The sons, all of whom are dead, were Thomas and Alfred, or Auckland, Richard, of Gisborne.
Mrs. Rowe claims that Mesdames Barker, aged 76, Stong, aged 72, and herself, aged 74, are entitled to share equally in the estate, as they are the only living members of the family of the late Mr. and Mrs. Bach.Mrs. Rowe bases this claim on the belief that at the time of her death her mother, Mrs. Bach's original share in the estate, valued at 20,000 (pounds), had increased to 80,000, by the death of her three sisters without issue.The money, Mrs. Rowe says, was never paid over, and, with interest, now amounts to about 250,000, to be divided between the three sisters.
The living members of Mrs. Rowe's family are Mrs. E. Hart, Perth, Mr. H. R. Rowe, taxi-driver, Thames, Mrs. L. Thomas, Hill Street, Thames, Mrs. S. Thornley, Great South Road, Auckland, Mrs. J. Carley, Bondi, Sydney, Mr. f. Rowe, Perth, and Mrs. O. Rogers, Subiaco Western Australia.The Thames members of Mrs. John Barker's family are Messrs. R. and P. Barker, of Kauaeranga, C. and H. Barker, of Thames, and Mrs. S. McDonald."
