Someone has submitted records to LDS (

Mary Ann Hunter (1826 Co. Cavan, Ireland-10 Dec.1889 Uniondale) married (18 Jan.1875) Frederick Thomas Stone (20 Apr.1829 Kensington, England-11 Nov.1907 Uniondale ). However, the following children are listed with dates well before the supposed marriage date-
1. William James Stone (16 Dec.1857-8 Sep.1932).
2. Frederick George Stone (15 Nov.1859 George, South Africa-6 Jan.1915).
3. John Thomas Stone (10 Feb.1862 George, South Africa-28 Sep.1919).
4. Edward
Arther Stone (17 Oct.1863-8 Aug.1928)
If the marriage date is correct Frederick and Mary Anne either got married well after all their children were born or the children were from a previous marriage. Like all subm itted LDS records each details would need to be verified.
