There is one online tree BUT it's somewhat up the pole so don't know what is actually fact.
It shows that Hilda Emily Shugar was married to a Henry Arthur Millard b.1889?? (although no marriage seems to exist) and they had a daughter in Sept. 1926 at Bournemouth (won't name as possibly still living but easily found in FreeBMD birth index - also appears to be the only child). It also shows that George Arthur Shugar b.1910 was Hilda's illegitimate son. So far so good. There is also a picture of Hilda so one would suppose the facts so far are correct.
A Hilda E. Millard b.1893 died Sept.qtr.1950 Bournemouth so that fits too.
A George Arthur Shugar b.30/7/1910 died Dec.1974 New Forest, Hampshire so that would also fit.
I cannot find a Henry A/Arthur Millard dying in the same area and indeed the tree shows he died in Gloucestershire (where he was born) so with no marriage cannot verify that his name etc. is correct.
Then the tree goes haywire - it shows she and Henry had a daughter Sybil Grace (now deceased) born in 1920 - however, Sybil Grace Millard was born in Mar.qtr.1920 Reading and her mothers maiden name was Broadhurst! Indeed, a Walter John Millard b.1895 Reading married a Beatrice Maud Broadhurst in June qtr.1917 Reading and they appear to have had a daughter 1917, Sybil Grace 1920, another daughter 1924 and a son in 1929. Clearly, we have two different families here and I find it hard to understand how the owner of the tree could make such a glaring mistake.
I would suggest you get the birth certificate of Hilda's given daughter born in 1926 (mmn Shugar) to verify that she was indeed the mother and also the name/occupation of the father (be it a Henry Arthur Millard or someone else).
Hope this helps.
