Adelaide Barnett Wilson (later Donovan and Milton)

Apologies for length but this is everything I know about Adelaide Barnett Wilson before juddering to a complete halt in 1876.
Born 6 Jul 1848 according to baptism record. Birth registered Jul-Sep 1848 Bethnal Green

1870 - aged 22, at St Dunstan and All Saints, Stepney, she marries Thomas Donovan, gentleman, aged 50 according to marriage record, but 60 according to census the following year.

They have three daughters. Thomas is recorded as a commission agent on their baptism records.

1871 census - in Lambeth, with Thomas and first daughter Chrissy

Chrissy's baptism record gives her full name as Chrissy Elizabeth Wilson Donovan. (She has an aunt Christian Elizabeth Wilson after whom she is presumably named.)
Chrissy and second daughter Adelaide Maude Donovan (birth reg Apr-Jun 1872 Hackney) are both baptised on 9 Aug 1874 at St Matthias, Stoke Newington.
A third daughter Maria Maude Mary Donovan (birth reg Oct-Dec 1874 Edmonton) is baptised same church on 8 Nov 1874.

1876 Adelaide, now widowed, marries William Milton, grocer, on 20 Feb 1876 at St James the Great, Bethnal Green,

After that, I can't find any trace whatsoever of Adelaide and second husband and the 3 daughters from her first marriage, nor find a birth reg for Chrissy. Nor have I pinned down a death reg for Thomas.
Can anyone help?
Thanks,
Christine

sorry - not sure why some records not showing as hyperlinks.
